I will ask it to the devs, maybe they know what to do.

You cannot alter permissions of system components.

Not even when rooted?
The question wasn't related to rooted devices. If individuals wish to root their devices and remove system components, break functionality, power to them. Your device is your device.
Doing so breaks the security model and is not an avenue I can spend time discussing as it can't be supported by us.
