Changing Time Zone on Child's Ipad to Avoid Time Restrictions

My child is changing the time zone on her ipad in order to skirt time restrictions on her apps. I have followed the directions on forum questions from 2024. In her ipad settings under Date and Time, it says "Setting the time zone automatically requires turning on Location Services". She is still able to toggle "Set Automatically" on and off even though under Content and Restrictions, no changes are allowed without a passcode. I have performed a hard restart of the ipad. What am I missing?
