Problems enrolling nvidia driver when /sys/firmware/efi/efivars is full

English Install/Boot/Login

As you can see above, there is a full path. Am I missing something?

I have now also tried

nvidia-pubkeys:bash$ sudo mokutil --root-pw --delete MOK-nvidia-driver-G06-550.107.02-26.1-default.der
[sudo] passord for root: 
Failed to delete keys

Also as real root without sudo

nvidia-pubkeys:bash$ su
Passord: 
localhost:/usr/share/nvidia-pubkeys # mokutil --root-pw --delete MOK-nvidia-driver-G06-550.107.02-26.1-default.der
Failed to delete keys
