If you were to ask, I’d have no idea how a Gender Sim would work. I suppose it would be a technological replacement for hormone drugs or something like that. A device that can be grown out of or that needs to be replaced every once in a while. The Titan Cluster would of course be the closest place to have sex reassignment surgery. Most of these kids have never left Eos before, and this small of a population wouldn’t have doctors who specialize in this field.
