[EFI] [GRUB] Reboot every time EFI boot variable is modified
My computer reboots every time I modify EFI variable.
I have found this after I installed (and then removed) Windows 7 (later versions failed to install with same issue). I have used efibootmgr to remove Windows‐related EFI boot variables. Every time I removed a variable, system rebooted, but variable was removed.
How can I install GRUB in this case? Is it possible to do some commands after each reboot until finished?

Which computer is affected (brand, model and version if applicable) ?
SAMSUNG RV508 laptop (neofetch says "RV408/RV508").
Some Phoenix SecureCore BIOS/EFI IIRC (non‐free, cannot replace).
If required, I may try to download Windows 7 ISO again (I deleted it) and install it temporarily.
