We can’t report bugs when a kernel is tainted so let’s hope Nvidia guys could fix it in the future.
The good news that this crash is happening only once during initial boot. Everything is working fine after the initial boot.
This very crash is related to plymouthd
~/# dnf list installed akmod-nvidia
Installed Packages

And we got crash in nv_drm_atomic_helper_disable_all function during plymouth init.
