Help! Unlink function and game guardian

Hi,
newbie to modding stuff (very easy), i'd like to know if there is a way through lua file using game guardian (dz...) to unlink a function of a game ? (ie: One hit ko not only for us but alos for the ennemy which we do not want.).
And if it's possible, may i have the right code to put on the lua file ?

I thank you in advance.
