How too disable PCMod2 tools in Q menu?

Hi i have a rp server it has a pctech class i make the pctech buy his tools from the pcbuy menu but its pointless because the tools in the Qmenu are free plus non pctech players can use them so the question is how do i disable them?

Some admin mods (Assmod) can disable the tools in the Q menu.

is there some sort of script someone can make real quick that can limit them too computertech class only? Thanks
