Two fiber connections in one home

So I want to have a second fiber wan in my bedroom to separate from my dads connection. Would I be able to run two att fiber accounts in the same house?

Edit - I would like to elaborate on my reason for this as it’s very niche. Essentially my dad likes to have complete control of the network and hardware to admin it himself and I also would like to continue building out my own homelab. He is fine with anything I do as long as it’s separate and I pay for it of course.
