I had a computer with 2080 rtx card and ubuntu got scrambled so went to install distros that were friendly to AMD processors with Nvidia card. Read about cachyos and it seems to be super stable. installed items via live-disc.
the dmesg error I see is

I have installed both dkms and cachyos-nvidia. I did load the modules per the nvidia Arch wiki as well as kvm and drm cat both showed Y.
It appears that nvidia-smi cannot find the driver
nvidia-smi
No devices were found
Also dmesg logs show
nvidia-uvm: Loaded the UVM driver, major device number 238.

How did you install the driver?
Can you provide sudo cachyos-bugreport.sh output?
