Unfortunately you can't spawn this boss in and kill it, you have to complete the Tek Cave instead.
Once you got teleported into the special room and the Overseer has spawned, spawn a Giganotosaurus in.

Beating the bosses in the right arena isn't needed for the achivements.
If you still want to get to one of these, here's a list with teleport commands.
