That could consist of a physical switch or jumper that must be manually

OR there could be a second boot ROM in the machine that could be jumpered
into place to enable booting, perhaps to a limited recovery mode, if/when
the primary boot is damaged.
OR, in worst case, the NVRAM could be socketed, and a replacement copy
could be physically installed.
YES, the part(s) could be unsoldered, and replacement soldered in. THAT
does not seem like an acceptable recovery requirement.
Why are such incompetent designers still employed in the industry?
It could be due to an unforseen situation not considered by the designers.
Several years ago a friend of mine bricked at CAR (BMW I believe---it was a
high end German car in any case). He was updating the firmware on the car
