Wait for 3D view to update after UI number slider changed

Magicians, I have a question considering the updating of slider values.

In my GH program, some UI Number Sliders should change geometry in an external GH file, this happens in the C#changeBlock component. In the green ellipse the 3D View of this updated geometry is shown. But by my believe the slider updates everytime the user slides one number up/down, which is not good considering processing time and the warning triggered in the below left green ellipse.

Is there a way in C#/python/GH to don’t trigger an update for every change in UI Slider value?

Thanks in advance.
