Correct, nvidia says supported but no dice.
I did a clean install of LM22.2, it would not see the 3 displays. I did update/upgrade/rebooted, same. sudo apt install nvidia-driver-470 installed but upon reboot no display. dmesg says I cannot find a GPU. I looked at dpkg -l | grep nvidia I saw 470 and 535 mixed together.
I installed LM 21.3 with nouveau, sees the 3 displays, I’m ok. No updates on this pc anymore. I put a HOLD on everything
