Config - Lovelace Dashboard

Hey lovely people.

I have a situation where i cannot find a solution online.

I have the default “overview” dashboard. I keep it managed automatically.
I have another dashboard where i experiment with the UI manually.
I have a dashboard for a non-admin user.

The user has the mobile app and going on the user profile, chosen the default dashboard for him.
But alas, the “overview” dashboard is still available to him. If he wants, he can access things I do not wish by changing the default view on his app.

Any solution please?
