Is there any ability to add focus settings on child iphone accounts to parental controls?

I am currently hoping my teen son doesn't catch that I added his school location to his focus settings and blocked entertainment and social networking apps. This would be a great parental control feature. Screen time is one way to limit, but location is clearly another, as are contacts as several of your threads indicate parents struggle to control. Anyone else have ideas for teenagers using games and social networking apps in school and not their productivity tools?
