This has been on my mind for a long time and it pokes at me more with shinobu and ana bray find out their past
And that question is simple why can’t our guardians find out their past life or even try to find out
It’s like an unwritten rule but why is it like that why?!

I would assume trying to find out about one's past is irrelevant and could possibly get in the way of the main objective: Protect the City at all costs. You hear Zavala talk about that when the Red Legion attacks the Tower and City, how the City and its people are prioritized over everything including the Traveler. So, It's a waste of time and doesn't really matter considering you've been dead for hundreds of years and everything about your past life is probably lost.
