Yes though in this [0] teardown there's a comment at the bottom that makes it sound like there's an easy connector where the SSD CPU connection can be accessed which would probably allow non-destructive imaging without involving the CPU so no userland software could protect against imaging.

> The funny connector to nowhere is the connector to tap into the SSD. When the Apple connector is mounted (as supplied) it connects the CPU to the SSD. When removed the signals for the SSD can be accessed.
