Just to avoid any confusion:
Normally, live tiles are activated by default, which means as soon someone installs an app, it will show up as live tile as long the app itself would support that, until the user deactivates live tiles at this certain app.
The thing I imagine though is the other way around:
As soon an app has been installed, the live tile is deactivated by default, but the user can activate it for a specific app if liked so.
Is that even possible to apply such a rule?
Everything I found really looked like to disable the live tile feature in general, so that it could not be used individually by users as painted before.
Disabling them completely would be useful as well though.
