Anybody have a stable Nvidia driver version running with 2x3090 on Ubuntu?

I’m having some major frustrations getting a new system set up. OS is Ubuntu 24.04.2 LTS; motherboard is MSI B860-P plus WiFi; and I have installed 2x3090s. I am using the integrated graphics for my monitor since I want the GPUs dedicated for compute.
Both 3090s are detected and I can see them in my system info but they aren’t being utilized. When I select the Nvidia 550 driver (from the Additional Drivers GUI) that says “(proprietary, tested)” it installs no problem but then my system has a meltdown over two reboot cycles after. One reboot I lose my Ethernet and WiFi completely and integrated graphics drops down to 1080p. The GPUs work great in OLLAMA on that first reboot but everything else is falling apart. A second reboot and the system will no longer boot into the OS.
I’ve reverted using Timeshift and repeated again with the same result. The second time through I tried to switch back to the x server driver but it still wouldn’t boot the third time. I’m hesitant to keep clicking buttons without an idea of what is happening or at least a better way of saving it than doing a full Timeshift recovery.
Should I try a 535 version? Maybe a server one? Should I install using the command line? Any help would be greatly appreciated. The dual 3090 setup seems to be quite common here so I’m hoping someone has a stable setup running that I can learn from.
