How to block a mobile device from the Mobile App integration

Hi folks,

My Home Assistance instance is being used by close to 10 people. So each of them has a separate account and is logged in via the Home Assistant app.
I am trying to find a way for their mobile device not to be tracked, in other words, not to have it under Integrations → Mobile App.
Regardless of whether I disable or delete their device in the below list, as soon as they open the app again, their device appears as enabled with the entities that it exposes (location, battery state etc.).

Is there some way that I can remove those so that they are not part of the devices/entities in Home Assistant?

why dont you just disable the sensors you dont want and leave it alone? or ask them to use the browser?
