Just a correction, this doesn't need different renders, just different dialog, which is a little easier, I know you meant in general but I think it is important to clarify just in case BD sees it. But I'll also say if the dev doesn't want to take a certain choice into consideration they need to either have a definitive end(either all the choices end kinda the same, or it is a self-contained interaction that will have no effect in the future), not give the player the choice, or just never introduce the "minor" characters, otherwise, it gives way to complaints, people getting attached, and many other problems.
