A repair business doing that wouldn't be in business for long though. There are APIs available for verifying whether FindMy is disabled for the device in question, that might be a better proof that the device is honestly sold to a repair shop for parts. For devices broken enough that they don't turn on there needs to be a way to remove them from FindMy without using the device though... is removing them from the list available at https://appleid.apple.com https://appleid.apple.com enough?
