Just close your eyes. The Face ID on an apple device won't unlock if you have your eyes closed.

But what if the bad guys "just" ask you not to close your eyes persuasively enough?

Try it. Use your hand to hold your eye lids up and see what happens.

edit* if you're talking about other means of persuasion, it's the same risk factor as if you had a PIN to unlock it.
