Alexander Deucher at AMD came up with a quick fix for the 5.15 branch, which I was able to test and verify - amdgpu_fb.c, line 344:

- if (!amdgpu_device_has_dc_support(adev) && !amdgpu_virtual_display)
+ if (!amdgpu_device_has_dc_support(adev) && !amdgpu_virtual_display && !amdgpu_sriov_vf(adev))

With this change, the amdgpu module loads and runs correctly on AWS EC2 G4ad instances. The change only affects datacenter cards with SRIO-V support and not consumer cards.
