If I understand correctly you would like to disable the possibility of the Slider to be edited manually by dragging it correct?
If that's the case, to my knowledge there is no out of the box solution for this.
I could think of 2 possible workarounds to handle this regardless:
1. The easier solution, bind ValueChanged Event for Increment and Decrement, on any change while the Slider should be constant reset the value to the one you want the slider to stay at. This won't prevent the slider to be dragged but it will allow overriding any change and reset it.
2. Implement a custom Shape and use a Label to display the current setting, use this shape in place of the Slider when you don't want it to be changed. More implementation intensive.
For both solutions you would have to "cache" the values and reuse them to keep the slider position.
