Hi all!
I have a similar problem with the same laptop of @fgfm03 . I tried to install ubuntu 20.04 in a dual boot system with Windows 11. I was able to install Ubuntu switching uefi mode to ahci instead of raid and disabling secure boot. I installed Ubuntu 20.04 with kernel 5.13 as default, but i could not boot and i solved adding nomodeset to the grub configuration but my wifi and bluetooth modules did not work. From there I installed kernel 5.18.8-051808-generic and that solved the issues with bluetooth and wifi boards, when i tried to install nvidia driver ( I tried from 470 to 515 using both ubuntu software&update tools and apt ) everything seems to go fine but when I run nvidia-smi it gives me this message: “NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.”
I tried to add “ibt=off” on grub configuration but it did not work both doing it before the driver installation and after.
I send you also my nvidia bug report.

Dell G15 5521 special edition
Ubuntu 20.04 Kernel 5.18.8-051808-generic

Any suggestions? thanks
