Grid K2 linux kvm driver (proxmox 7.1, kernel 5.13)?

Hi guys,
I have a server running proxmox 7.1 (debian os, kernel 5.13). I applied for the trial vgpu license but I am not able to install a driver. The latest driver refers to 367.xx linux legacy driver which I downloaded but crashes upon installation when trying to compile the kernel module.
Any hints how to make that work?

Serious? K2 is EOL since 2018 and 367 branch was the latest to support this GPU. We are now at 470 branch. I would recommend to buy a decent GPU first.

Regards Simon
