Just download the Halo E3 Demo from the workshop, when it finish downloading start your game from your library, click play and it will ask you if you want to play with or withour anti-cheat.
Or you can change the default option, just go to your library (Halo TMCC), go to settings/properties and right there you just search for "Selected Launch Option", teres gonna be 3 options, ask when starting game, play with anticheat and play without anticheat.

I hope this can help!!!
