HSM or disk encryption keys (e.g., the encryption keys in Apple silicon) should be stored in a space that is intended to be impervious from analysis techniques (SEM, X-ray, etc) and any deprocessing technique (acid removal, FIB, etc) will destroy the contents. It's built differently from traditional techniques. I suspect this fancy X-ray would not work either.
