The Chosen will not teleport into a mission so long as you have squad-wide Concealment up. So if you have the Alien Hunters DLC, turn on Integrated DLC, and prioritize taking out the Alien Rulers, you'll almost never encounter the Chosen in an Avatar Project Facility -which is a bit unfortunate as they have dialogue specific to such missions! If you use Integrated DLC, this has the consequence of meaning they're sort-of forbidden from showing up in Avatar Project Facilities, since Alien Rulers will assign themselves to three of them as the opportunity becomes available, and it's not unusual for a run to only need to hit 2-3 Facilities in total. Another qualifier is that Chosen are forbidden from spawning into a mission that at any point had an Alien Ruler in it. The exceptions are the DLC missions (The Tower and the Nest), the second-to-last mission of the game, Avenger Defense missions, Covert Operations for rescuing a captured soldier, Ambushed Covert Operations, and also they'll never drop into another Chosen's Stronghold when you attack it. First of all, the Chosen can show up in virtually any mission of the game.
