I only know how to get around my employer’s device settings for iOS. I would have to have access to your phone to try to get around them

The issue I have with your comment is “a child isn’t going to find a way around it” I was much more motivated to find a way around settings my parents set on devices when I was a child, and I definitely shared how to do it with my friends

Maybe your settings are secure, but it’s not trivial for most parents
