Uhm disabled how? The commands that the menu uses shouldn't work on the regular server, unless maybe you have a GM/Dev account there.
I don't think there's an easy way to disable the menu itself, since it is a rather "dumb" command. Basically, don't create a macro for it on the regular servers and you should be golden. (If you share bindings and power set ups on both Justin and regular servers, try not to save the Justin side of things)
