That one did not happen to me. efivars directory is an interface that
exposes EFI firmware variables. If you do not see the dump files in the
directory, then EFI should have cleared them. However, in such case the
memory would be freed for new variables, and you would not get the
error when reconfiguring the system anymore.

There are other ways to access the variables. You could try efivar to
see whether the dumps are still reported by UEFI.

$ guix shell efivar
[env]$ efivar --list
[env]$ exit

The tool also allows removing variables, but I did not try that myself.
