Sorry no you can't and I don't know if it can be added since bernard is now a part of the overarching story of logan and any more werewolf related content.
ya it would be nice to have that for the people who aren't romantically interested in bernard it could still start in the cottage in the forest like the other route but just add an extra option and then the bath house and such but just another option that puts you in a more friend position instead as a lover thats at least how i thought about it so that it wouldn't be too big of a change. but ya if You could do something like that it would be appreciated.
