Child turning location via contact information in find my

I have blocked all the changes so my child can't turn off her location, via settings/screen time/content and privacy/location services and also in the settings from my child's phone via privacy and security.

The issue here is that my child can still turning off the location, via the app found my, then go to my contact info and bellow there is the option stop sharing location.

How can I block this option?
