Your kernelopts in the env don't match the /proc/cmdline.

Yes.   How can that be ?

Can you boot and then check/edit the "linux" line?

You mean cat  /proc/cmdline ?

How do I edit it ?

 

The most important part is "rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1"

Agreed.

And boot including those parameters? 

How ?   I was comfortable with grub, but I'm lost with these new boot systems.

Also, you would want to check /var/cache/akmods/akmods.log to ensure the driver for the running
kernel is built.  The driver itself will be located in /usr/lib/modules/`uname -r`/extra/nvidia
