If they have the right AMD drivers it should in theory work for linux based on how it's detected of literally dumping strings and looking for the field.
MacOs doesn't use NVIDIA in any recent years nor AMD they create their own now I believe and also I believe on macos only supports onegpu. The GPU being either intel iris neither integrated nor dedicated, or their own
