Numan internet Radio based on Frontier Silicon question

I got this Numan Internet Radio device, which works well with the Frontier Silicon integration for the basic features,
In addition, this device has the ability to turn the display on and off with a button. I wonder if this is a hardware button only or if it´s possible to somehow use this feature in home assistant?

Have a nice sunday,

Hi Philipp,

can you control the function with the undok app? If not there I don’t see a way to do so
