I don't think that it is necessary because you can just cancel the download of mods, signs and music ingame. Then the game jumps directly into the map.
But it downloads the mods while you play the map in the background.
If you want to disable download of content from others at all (avatars, mods, skins) you can disable it in the launcher settings
