• Negative pregnancy test for women of childbearing potential (WOCBP) within 72 hours of starting therapy
• Must not be breastfeeding
• Woman of childbearing potential: Must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug(s) and up to 5 months post last dose of study drug(s).
• Men: Must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug(s) and up to 7 months post last dose of study drug(s). Must be willing to refrain from sperm donation during this time.

Exclusion criteria

• Must not be currently receiving study therapy or have participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment.
• Must not have had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or have not recovered (i.e. < grade 1 at baseline) from adverse events due to agents administered more than 4 weeks earlier.
• Must not have had prior chemotherapy, targeted small molecule therapy, radiation or other anti-cancer therapy (with exceptions for disease-specific hormone treatments considered standard of care) within 2 weeks prior to study Day 1 or have not recovered (i.e. < grade 1 or at baseline) from adverse events due to a previously administered agent. Exception for ≤ grade 2 neuropathy. If patient received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
• Must not have known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they are stable, have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment.
• Must not have had prior radiation therapy (defined as >10% of prior prescription dose) to the area planning to be treated with SBRT.
• Must not have a diagnosis of immunodeficiency or is receiving systemic steroid therapy at a dose of >10 mg prednisone daily or equivalent at time of first dose of trial treatment.
• Must not have a known history of active TB (Bacillus Tuberculosis)
• Must not have hypersensitivity to nivolumab, urelumab, cabiralizumab or any of their excipients.
• Must not have a known additional malignancy that could confuse analysis of on-study treatment. Inclusion of all study participants with more than one malignancy must be discussed and approved by the PI.
• Must not have active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroids replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
• Must not have a known history of non-infectious pneumonitis that required steroids for treatment.
• Must not have evidence of interstitial lung disease.
• Must not have an active infection requiring systemic therapy.
• Must not have a history or current evidence of any condition, therapy or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
• Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
• Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 120 days after the last dose of trial treatment.
• If known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA [qualitative] is detected) then patient is not eligible for cohorts including SBRT to liver lesions.
• Participants must not have had prior organ allograft or allogeneic bone marrow transplantation.
• Participants must not have had uncontrolled or significant cardiovascular disease including, but not limited to, any of the following:

• Myocardial infarction or stroke/transient ischemic attack within the past 6 months
• Uncontrolled angina within the past 3 months
• Any history of clinically significant arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or torsades de pointes)

• Cardiovascular disease-related requirement for daily supplemental oxygen therapy
• Has received a live vaccine within 30 days of planned start of study therapy.
• Participants may not concomitantly use statins while on study. However, a patient using statins for over 3 months prior to study drug administration and in stable status without CK rise may be permitted to enroll.
• Participants may not have current or history of clinically significant muscle disorders (eg, myositis), recent unresolved muscle injury, or any condition known to elevate serum CK levels.
• Must not have a history of allergy to nivolumab, urelumab or cabiralizumab.
• Must not have a history of any significant drug allergy (such as anaphylaxis or hepatotoxicity) to prior anti-cancer immune-modulating therapies (eg, checkpoint inhibitors and T-cell co-stimulatory antibodies).
• Must not be prisoners or be involuntarily incarcerated.
