How to disable F1 - F4

I guess this quetion have been asked over and over but I couldn’t find topic so let me ask once again here.

I built 64e and everything works fine,

now I want to disable F1 - F4 and use like other buttons on Ableton live MIDI map.

Could anybody let me know any idea which inc I should change or any page explain about it?

Thank you
