If I recall correctly, voices requiring native CUDA support on FreeBSD was far more larger (huger?) than now, but it quickly shrunk once it turned out that FreeBSD can run Linux CUDA apps via Linuxulator and linux-nvidia-libs.I was initially looking for that too, no change for 15 years so not gonna happen Turns out FreeBSD's Linuxlator is already so good it can do this sort of tricks
So it would be unlikely.
This is why I'm habitally sending patches for x11/linux-nvidia-libs with x11/nvidia-driver (and recently graphics/nvidia-drm-[||]-kmod, too) even though I myself am not using x11/linux-nvidia-libs.And by my initial experimentation it is very important that nvidia drivers and libs have the same version, so having all this stuff in ports keeps things in sync
