I have accumulated a few cast-enabled devices in my network. For example I got a Chromecast with Google TV which is connected to my TV and my main device I use to stream too.
In the same room I also got a Nest Mini, which I never cast to, and I really want to remove this device from the list of available devices (in the casting list on your phone).
Same thing with my Samsung QLED TV. I notice that in some apps, like the Youtube app, the Samsung TV shows up as [TV] Samsung Q9F. I never use this device for casting, and I would like to remove if completely from the list.
Sadly I cannot disconnect it from the network as I still use a few features that requires a connection.
I cannot move it to another subnet, as this will disable a lot of other functions.
Any idea on how to disable the casting ability only? Is there any firewall rules I can use for this?
