I don't know. I don't think it will have any effect. It is UEFI that
refuses to take a new variable. You need to find a way to make it take
the variable.

The first time it happened, I rebooted and was unable to boot. GRUB
did not show up. And selecting the Guix boot option in UEFI boot menu
failed to load GRUB. I had to use a Guix installation USB drive to
chroot into my installation (section 12 of the guix manual) and fix it.

The second and third time it happend, I cleared the dumps via efivars
directory the way you did. This allowed me to complete reconfiguring
the system each time. It looks like my UEFI behaved better then yours.

I do not know whether you can properly roll back the guix system to the
last (meaning current) configuration, so that the existing boot option
works. Maybe somebody else could comment on this.
