Anybody Done GPU pass trough on Nix?

I've found a few guides but most of them or hard to understand or poorly written, I've done pass trough on proxmox and Arch Linux.

I tries this guide but no luck

I've done single-GPU passthru in NixOS. It's not any different than on i.e. Arch, just that you configure some basic setup things such as kernel parameters declaratively using NixOS options.

I highly doubt your issues are NixOS-specific, so I'd recommend you ask about them in the general channels.
I've had VFIO passthrough setup on a NixOS host before without issue. While this guide isn't the one I followed it is an accurate and good guide.
