Unfortunately I don't know any project which has this implemented. However on libreelec I can go to the libreeelec settings -> Bluetooth and see my different controllers. Those controller are shown as connected (yes) or not connected (no) and there I can disconnect single controllers (option is called disconnect - I have no idea what enable standby is supposed to do, but disconnect works!)
Couldn't this be used by you?
