It is a Raspberry Pi. It is an ARM computer, not an x86 PC. The Pi
does not use EFI; it does not use a bootloader at all. The system is
controlled by the VideoCore GPU which runs the Microsoft ThreadX RTOS
and after that boots, the GPU loads the Arm OS from a FAT32 partition
then starts the Arm and passes it the OS image as a payload.

No, not on a Pi.
