Hi,

there is no file on your Linux. It's provided by the firmware.

Btw. instead of pushing the del key, pushing the del key, pushing the
del key, pushing the del key, I'm using a GRUB menu entry to open the
UEFI settings dialog.

$ grep -i firmware -A2 /boot/grub/grub.cfg 
menuentry "    UEFI Firmware Settings" --id 'uefi-firmware' {
        fwsetup
}
