Hide the switch for rebooting the Fritzbox
**Is your feature request related to a problem? Please describe.**
The switch for the Fritzbox reboot is very dangerous. It is very easy to press the switch without purpose. 

**Describe the solution you'd like**
It should be possible to hide the switch to reboot the Fritzbox with a configuration preference like the other switches.

**Describe alternatives you've considered**
There is no need for this switch. It could be deleted from the code.
