BlackWidow V3 Pro FN key lighting

I have a BlackWidow V3 Pro since a few weeks now, and I was fiddling around a bit in Chroma Studio just now and I can't figure out how to change the lightning on a certain button press. What I mean with this is like when you hold the FN key the hotkeys for the FN key are shown and the rest of the lighting is off. Is this even possible to omegle change, or am I not able to change that?
