Installed Packages
nvidia-gpu-firmware.noarch                20230404-149.fc38                 @updates

Should I uninstall nvidia-gpu-firmware.noarch , simce it should not be needed?

4

No.
It would just get reinstalled with the next firmware update. The firmware packages are available for almost all possible devices but only used for the ones actually available. If you intend to start removing firmware then (IMHO) you have to be really desperate for space. /lib/firmware (which contains all the firmware) uses <300M on my system.

5

Any idea what could be causing the flickering?

6

If it flickers when using wayland but not when using xorg then it seems somehow to be wayland related. I cannot narrow it down any more than that for you.
There are a lot of pieces involved in a DE that may contribute.
