How can I remove the loot and scroll menu from zombies

I am trying to stop loot spawning on zombies and I would also like to remove the option to scroll on a zombie ie: gear, hide body etc.. I want there to be no option when you look at the corpse.

Anyone know how I can do this? Any help is greatly appreciated. Thanks in advance.
