Support Disable haptic feedback wothout using Power saver?

Does anyone know how to disable the haptic feedback on the L9 'Back' and 'Menu' buttons? The only way I found was to use the power saver "Vibrate on touch" disable option and have power saver mode always on. But then I can't use power saver like it was meant to be used.

thanks,
Max

 

I found it under

Settings > Sound, at the bottom.

I guess I didn't scroll down all the way during my first search. I didn't expect it under Sound, but not sure where else I'd put it. My first thought was Language and Input.
