Active comparator: Arm I (standard of care immunotherapy) - Patients receive one of the following immunotherapy regimens per physician discretion: nivolumab IV over 30 minutes and ipilimumab IV over 30 minutes every 3 weeks for 4 doses followed by nivolumab IV over 30 minutes every 2 or 4 weeks; pembrolizumab IV over 30 minutes every 3 or 6 weeks and axitinib PO BID; avelumab IV over 60 minutes every 2 weeks and axitinib PO BID; nivolumab IV over 30 minutes every 2 or 4 weeks and cabozantinib PO QD; OR pembrolizumab IV over 30 minutes every 3 or 6 weeks and lenvatinib PO QD. Treatment with immunotherapy continues in the absence of disease progression or unacceptable toxicity. Patients also undergo CT scan or MRI throughout the trial. Patients may also undergo a bone scan as clinically indicated and blood sample collection throughout the trial.

Experimental: Arm II (SABR, standard of care immunotherapy) - Patients undergo SABR on 3 different days over 1-3 weeks and receive immunotherapy as in Arm I. Patients also undergo CT scan or MRI throughout the trial. Patients may also undergo a bone scan as clinically indicated and blood sample collection throughout the trial.

Eligibility
Key inclusion criteria
* Pathologically (histologically or cytologically) proven diagnosis of renal cell carcinoma prior to registration
* Node-positive unresectable (TxN1Mx) or metastatic (TxNxM1) based on the following diagnostic workup:

* History/physical examination within 45 days prior to registration
* CT/magnetic resonance imaging (MRI) of the chest/abdomen/pelvis within 45 days prior to registration
* Patients must have IMDC intermediate (1-2 factors) or poor risk disease (>= 3 factors)
* Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
* Patients with measurable disease (node positive or metastatic) as defined by RECIST version 1.1 excluding the primary renal tumor
* Patient not recommended for or refused immediate cytoreductive nephrectomy
* Candidate for standard of care therapy with either immuno-oncology (IO)-IO or IO-VEGF combination regimen
* Primary renal tumor measuring 20 cm or less in anterior to posterior dimension only on axial imaging
* Age >= 18
* Karnofsky performance status >= 60 within 45 days prior to registration
* Hemoglobin >= 8 g/dL (transfusions are allowed) (within 45 days prior to registration)
* Platelet count >= 50,000/mm^3 (within 45 days prior to registration)
* Absolute neutrophil count (ANC) >= 1500/mm^3 (within 45 days prior to registration)
* Calculated (Calc.) creatinine clearance >= 30 mL/min (within 45 days prior to registration)

* Creatinine clearance (CrCl) >= 30 mL/min estimated by Cockcroft-Gault Equation
* For African American patients specifically whose renal function is not considered adequate by the formula above, an alternative formula that takes race into account (Chronic Kidney Disease Epidemiology Collaboration CKD-EPI formula) should be used for calculating the related estimated glomerular filtration rate (GFR) with a correction factor for African American race creatinine clearance for trial eligibility, where GFR >= 30 mL/min/1.73m^2 will be considered adequate

* Moderate or severe hepatic impairment (Child-Pugh B or C)
* Any history of untreated pulmonary embolism or deep venous thrombosis (DVT) within 180 days prior to registration. (Any asymptomatic or treated pulmonary embolism or asymptomatic treated deep venous thrombosis > 30 days prior to registration is allowed)
* Unstable cardiac arrhythmia within 180 days prior to registration
* History of abdominal fistula, gastrointestinal perforation, intra-abdominal abscess, bowel obstruction, or gastric outlet obstruction within 180 days prior to registration
