Help with DarkRP removing DarkRP Module

Hello, I am trying to implement a custom Agenda script that I created. In order to do this I need to completely remove the old agenda system. Or at least the chat commands that the DarkRP gamemode has with it. I did something similar to this before, (This was reverting back to the old advert system, witch can be done by simply by going into garrysmod/gamemodes/darkrp/entities/entities and removing the darkrp_billboard folder, then implementing the old system back and changing the command to /advert. This works because the entity folder also contains the command function). Anyways does anyone know where the file is for the agenda command. Many Thanks

I also ask that you don’t ask me why I want to do this. My methods are weird but they work ok.
