Note: Prophylactic antimicrobial treatments (antibiotics, antimycotic, antiviral) are allowed. * Known infection with acute or chronic hepatitis B or C, known human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS)-related illness except for participants meeting all of the following criteria: (1) on stable anti-retroviral therapy; (2) CD4+ T cell count ≥ 200/µL; and (3) an undetectable viral load. Note: HIV testing will be performed at screening if and as required by local regulation. Note: To be eligible, participants taking CYP inhibitors (eg, zidovudine, ritonavir, cobicistat, didanosine) or CYP3 inducers (efavirenz) must change to a different regimen not including these drugs 7 days prior to initiation of study treatment. Anti-retroviral therapies (ART) must have been received for at least 4 weeks prior to the first dose. Note: CD4+ T cell counts, and viral load are monitored per standard of care by the local health care provider. Following illnesses/conditions are also excluded * Serious non-healing wound/ulcer/bone fracture.

Participants with durvalumab related adverse event can be included in the trial as long as participants are not requiring prednisone (or equivalent) \> 20 mg daily dosing. * Pregnant or breastfeeding women are excluded from this study because durvalumab and zanzalintinib has the potential for teratogenic effects. Because there is an unknown, but potential risk for adverse events in nursing infants secondary to treatment of the mother, breastfeeding should be discontinued if the mother is treated on clinical trial. These potential risks may also apply to other agents used in this study. * Radiation therapy for bone metastasis within 2 weeks, any other radiation therapy within 4 weeks before first dose of study treatment. Systemic treatment with radionuclides within 6 weeks before first dose of study treatment. Participants with clinically relevant ongoing complications from prior radiation therapy are not eligible. * Concomitant anticoagulation with oral anticoagulants (eg, warfarin, direct thrombin inhibitors ) and platelet inhibitors (eg, clopidogrel). Note: Participants must have discontinued oral anticoagulants within 3 days or 5 half-lives prior to first dose of study treatment, whichever is longer. Allowed anticoagulants are the following: * Prophylactic use of low-dose aspirin for cardio-protection (per local applicable guidelines) and low-dose low molecular weight heparins (LMWH). * Therapeutic doses of LMWH or anticoagulation with direct factor Xa inhibitors rivaroxaban, edoxaban, or apixaban in participants without known brain metastases who are on a stable dose of the anticoagulant for at least 1 week before first dose of study treatment without clinically significant hemorrhagic complications from the anticoagulation regimen. * Any complementary medications (eg, herbal supplements or traditional Chinese medicines) to treat the disease under study within 2 weeks before first dose of study treatment. * Clinically significant hematuria, hematemesis, or hemoptysis of \> 0.5 teaspoon (2.5 ml) of red blood, or other history of significant bleeding (eg, pulmonary hemorrhage) within 12 weeks before first dose of study treatment. * Lesions invading major blood vessel including, but not limited to, inferior vena cava, pulmonary artery, or aorta.
