They took the GUN out of experimental temporarily for the next stable update. It should be back soon. As for disabling the GUN before the Sunbeam arrives that will be practically impossible without using cheats. You still need to explore every base and cure yourself before you can get into the GUN control room.

Also, lets face it. If you saved the Sunbeam before you cured yourself you would spread the Carar to the rest of the human populations and potentially wipe out our species. Not exactly an ideal way to go...
