Note how the insertion of the KeyTool entry causes an extra entry in BootOrder AFTER a reboot.
Neither removing duplicates, deleting bootorder or setting bootorder will fix the issue when a reboot occurs.
It is only when I remove the added bootentry that the bootorder goes back to normal.

The changes of BootOrder after reboot are from the UEFI BIOS implementation.
