Feature request: toggle "Do not disturb" modes

[Iey4iej3]

Feature description
I hope that it is possible to toggle (or even tune) "Do not disturb" modes.

Background information
This seems possible, according to answers at https://stackoverflow.com/questions/31862753/ but I don't know whether they are still up to date.
This is useful when I want to set a timer then keep the device "Do not disturb" during this period.
