re: Adam Mercer's suggestion:
grubby --update-kernel=ALL --args="rd.driver.blacklist=nouveau
modprobe.blacklist=nouveau nvidia-drm.modeset=1"
Grubby is already returning the right kernel parameters. Not sure why I would need to run this.

be used by grub2-mkconfig, not grubby.
So I ran this:
# grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
Generating grub configuration file ...
Adding boot menu entry for EFI firmware configuration
done
Generating grub configuration file ...
Adding boot menu entry for EFI firmware configuration
done
and it made no difference.

See the reply from Adam Mercer. He gives the whole command line argument.
As far as setting /etc/default/grub LINUX_CMDLINE args, those appear to
be used by grub2-mkconfig, not grubby.
