I don’t know that the above line from your /etc/default/grub is causing a problem, but each entry there should only occur once. I would suggest changing that to
GRUB_CMDLINE_LINUX="rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1 rhgb quiet"
Once the change is made then rebuild the grub.cfg file with
sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
The lsmod command clearly shows the nouveau driver installed even though it is blacklisted in the kernel command line. The intel driver (i915) is for the intel graphics part of your laptop, and I wanted to verify it was loading properly.
That message seems strange with what you have installed.
I guess it is possible that not everything needed for proper building of the kmod is correctly installed or that something was corrupted, so I suggest the following.
sudo dnf erase akmod-nvidia kernel-devel kmod-nvidia --noautoremove
sudo dnf install kernel-devel akmod-nvidia*455* kernel-headers
I am assuming you are running the latest kernel (5.9.13 or later) as the nvidia module will be built for the kernel actually running when the above is done.
If a reboot after doing the above does not properly start the nvidia card then go back to the bios and verify that secure boot is disabled as stated by the rpmfusion howto since the nvidia driver taints the kernel and secure boot can prevent loading it.
If all the above fails there is also a dedicated optimus howto at rpmfusion that could be used as a last resort.
