"but they will disable some features if you are not using Radeon FirePro"
what are these?
PS: My 2080ti (MSI Trio) is on the way to me 
What I am saying is that Nvidia disables GeForce driver on VM, but AMD does not. Instead, AMD disables a couple features according to the forums, but the GPU should still work. That only happens if you are using AMD gaming GPU without setting your KVM model to "host." If you are spoofing the GPU, you should be fine either way.
