I believe that this is referring to the NVRAM on the motherboard not the boot disk.
I also believe that. NVRAM on an older machine may have limited space, so if cruft has accumulated the NVRAM could be full. See: https://ruuucker.github.io/EFI-Basics-NVRAM-Variables/
I had this happen to one of my machines and the fix was to reset the efivar’s on the motherboard and setup efi boot again.
From https://en.wikipedia.org/wiki/Nonvolatile_BIOS_memory: "by many OEMs https://en.wikipedia.org/wiki/OEM' design, the UEFI settings are still lost if the CMOS battery fails." So removing the battery may free up space.
