You realize that with UEFI (ed: on x86... yes, Windows RT devices are different), you can either disable Secure Boot or (at least on some systems) replace the root key with your own, without any hardware modification?
On Chromebooks, which I'm a bit more familiar, you cannot, and disabling verification involves a 30 second delay on boot with beep, to prevent against evil maid attacks. However, apparently it's not too hard [1] to flash the ROM on some devices if you can open the thing.
