Surely the relevant phrasing is
No person may operate the controls of an aeroplane who does not have an appropriate licence and rating except in the course of receiving flight instruction or at the direction of the pilot in charge.
And.
Any crew member or passenger must obey any reasonable order or instruction from the pilot in charge.
No I don'y know the chapter numbers.
I reckon it's okay to order your passenger to hold the controls. If they do it wothout permission, have them arrested.
