Does UTCOMP PRO have a dim display function when the vehicle lights are switched on?

I did not find reference in the online manuals or any input in UTCOMP PRO harness for illumination that can activate a dim function.

Yes it has based on pin A21 (it is shared with cooler input so you should pick up one: cooler input or headlights input)
Next in settings -> Display -> Dimmer set enable. And then you can set 2 brightness mode (it will switch when headlights are switched)

I see, I misunderstood and thought that was an output, not input.

Thank you for clarifying!
