How to use NVIDIA V100/A100 GPUs?

Hey guys, sorry to wake-up this thread, but in 25.05 or 25.11, what are your .nix configuration to enable the V100/A100?

(My A100 GPUs require nvidia-fabricmanager. I have tried datacenter.enabled=true and other definitions, but the nvidia-fabricmanager gives an error of undefined symbols :confused: .)
