Beastman tribe Trust

I wonder if it is possible to attain a Beast Tribe "trust" a.i by doing the beastman tribe quest lines attain full trust or furthering the establishment with the opposing beast tribe that worships their eikon to somehow either attain a trust a.i or companion to choose their "role" and each different tribe can play different, hence everyone worked together to deal with the "Final Days" during Endwalker.
Also, I do not think it is a bad idea to implement a.i trust from beastman tribe because that would be unique with all the hard work to earn their full trust.
