More or less. In my jurisdiction you can be compelled to give up biometrics, which has been expanded to include biometric unlocking. However, it requires a separate authorization, which in many cases will take long enough for the paperwork for TouchID to time out, and passcodes cannot be compelled (again, in my jurisdiction). There is no such protection for directing you to look at your phone.

For clients under investigation who have FaceID or similar unlocking for phones or computers, we always recommend they disable it and just use a passcode until the investigation is complete.

Like you advise your clients, no matter what the law says, you can't be compelled to unlock your phone with FaceID if you don't set up FaceID on your phone. I don't understand why this would prevent you from buying one.
