Hi all, new to Proxmox, so apologies if this is common knowledge

I recently added a RTX 2080 to my Proxmox server, and was installing the Nvidia drivers within the main Proxmox environment when I ran into a section stating that the public signing key needed to be added to the database in order to continue. I did a bit of research and ended up adding the key via:
mokutil --import keynote.der

After which, I was able to verify that the key was awaiting enrollment with:
mokutil --list-new | grep nvidia -i

However, the issue that I'm running into is that when I reboot the server to finalize the enrollment process, I no longer get any video signal from either the gpu or the motherboard. Because of this, the system seems to default to booting as normal, skipping the enrollment process and rendering the drivers unusable. Im assuming that this is due to the installation process blacklisting nouveau, however, my attempts to re-enable it have failed. Any ideas on where to go next?
