Parental control and dual apps

[jacopo3001]

My son is 14, and unfortunately - like many - exposed to problems of addictions to screens.
As a parent I need to help him develop healthier habits, sometime with carrot sometime with stick.
Parental control screen time feature are one of the tools I should have available to do so. Unfortunately xiaomi has builtin few "privacy features" which help any young teen bypassing parental control, namely dual apps and second space.
Is there a way to block/remove these features completely?

I cannot believe that I am the first parent in the world having this issue...

Nope.

I found both activities are part of "System Features Plug-in" (com.miui.securitycore), which by looking at the name doesn't seem very safe to just disable as a whole (please correct me if wrong).

Then, can I just hide these activities without necessarily disabling them? I know there are plenty of hidden activities (those you'd see through Activity Launcher, for example).
How can I hide some?
