Provide a way to choose gpu?

[netbrain]

NixOs nvidia-container-toolkit have been broken for some time now, atleast on my machine.

So when running zwift i get

However as i have a laptop with dual video cards (nvidia/intel) if i run the docker command without the --gpus=all it will choose to run on my intel card instead, and work just fine albeit with less framerate.

So this got me thinking, maybe we should provide a way to choose which graphics system to try to run the container with?

WDYT @sHedC ?
