Ability to disable auto discovery

Hi,
I have two Homeassisant setup, one in my home and one in the office, and the office is actually a service center where the team test and diagnose different devices daily. The problem is that whenever the team power up and connect one of those devices to Wifi it gets discovered by HA and I end up with an extremely long list of devices that belongs to customers and we are not able to remove from the interface. This is especially true for TV stick and we have to manually remove each one of those entities.

It would be great if there is a way to disable auto discovery for all or specific integrations to avoid such issues as it gets frustrating to have to do this every few days with a long list of newly added entities.
