Posted on Steam Community, a modder by the user name [Lebowski]-=ThArK=- created a mod that basically removes the xenomorph from the game, allowing curious players to explore the Sevastopol without getting munched on.
What the mod does is it makes the alien not move or act, keeping it in a vent. Whether or not this means the alien still can be found isn't known or if it kills you if you do come across it. It should also be noted that human and android enemies will still be around and will try and kill you like normal.
