Does HC550 has firmware encryption lock is I change PCBA and magnetic head?

My friend has a same model of WUH721816ALE6L4 hard drive and need to repair because of a small shock damage.
It needs to replace the PCBA and magnetic head, but the data recovery company said the data has been crypted because the change of PCBA and magnetic head, and HGST firmware will encrypt data if you change them. Is it real? Does HC550 has firmware encryption lock is I change PCBA and magnetic head?
I can’t search out any documents about HC550 firmware encryption lock.
