Does this work? I can't find anything showing how

I used to use them for mining with gpus.
It may come down to the os on the nuc(windows def allows it).
You’ll also need a psu for the riser & gpu so you’ll need a psu jumper.
I'll check on proxmox., especially pass through to the VMs. I'm assuming pass through works, but will need to verify of the USB plug will work for that
