Currently no. The dev is planning to add a Riesel route to stop her from getting NTR'd, as response to player feedback, but it'll be in a few months since he has to write the whole scenario and get voice acting. He'll also add a way to stop Dwarf NTR and a recollection room, which will take less time but will have to wait until there's no more major bugs getting reported.fuck..
Theres no way to get around it? she's my fav!
