eGPU through Oculink: modprobe: ERROR: could not insert 'nvidia_current': Key was rejected by service

I am running Proxmox 8.2.4 (ubuntu 22.04 base kernel) and trying to install a 3090 via Oculink. I have tried multiple ways to install the nividia-driver, but I can’t seem to get the driver to load. Now, I fully understand this might just be a Oculink compatibility thing, but I am stuck and not sure where to go next.
