Limited media browser access

Hey!

Does anyone know if it’s possible to limit media browser content to certain users?
I’ve seen ppl in other threads expressing security concerns due to cameras living in there, but my use case is a little bit different.
I have two spotify accounts set up. Mine and my sons.
My sons account is set to not allow explicit content.
Both accounts are browsable through the UI.

Is there maybe a card that targets a specific media source that I could put on a dashboard and lock him to that or something?

Unfortunately, there is no way that this could be done.
