[Request] Hide system language item from bios menu

I have Asus zenbook 14x laptop and now I am trying to hide system language menu from top header and Advanced/Main menu.
I was using afuwin (extract rom file) and amibcd to edit rom file.
But when I am trying to re-flash using afuwin it keeps showing me Unable to load from specified file error.
I have no idea how to fix this.
Please anyone help me to get this working. :smiley:
