I believe it’s in their T2 chip, which means that unfortunately, the only way to fix it is to swap the entire board. The CPU and T2 chip are serialized, as well as a bunch of other components. Also, the drive is encrypted by the T2 with encryption keys that are specific to that particular T2, so unless you replace everything including the drive, you can boot from neither the SSD nor an external drive.
The T2 will not allow you to read most of the data and it will erase itself if you try, so there’s no real way around it unless someone finds a bootrom exploit or something else that’s extremely low level.
