This is done supposedly through a checksum verification as well, so even if you code it back to stock it knows how many times a module has been written to, and if it doesn't match with the number of times BMW has logged it can be trouble.
Again, not saying it's true, but from things I've been reading while researching coding for ID8. I'm actually hoping for it not to be true so I can code my own car eventually.

BMW dealer must have tools that allow them to do a lot of things in the car's computer.
When I paid to have the oil changed at 1000 miles for peace of mind, I specifically told the service advisor and the tech NOT to reset the oil counter(or whatever they called it). The service advisor even had it printed on the invoice. The reason was that I didn't want the the car to wait another 10,000 miles before alerting me to another oil change(which would be free under BMW's free 3-year maintenance)
However, when I picked it up, sure enough, the tech had forgotten about it and the counter was reset. I went back a few days later and asked the tech about it. He apologized and said that he had too many cars that day. He drove it into the service dept and hooked it up to the biggest diagnostics computer I had ever seen(about the size of a portable air conditioner on wheels. After 10 minutes, he brought the car out again and the oil change interval was reduced by about 1000 miles.(or back to what it should have been) He said he was able to "cancel" the reset that he did, so the car "forgot" about that oil change.
