I765 and I131 USED TO always come as a Combo Card (if you did not mess with the application and try to expedite either of them).
Biometrics are needed for the I765 which came as a Combo Card so yes, you need biometrics for I765. I131 was automatically adjudicated together if you applied for it together. So yes, because you applied for both you need biometrics to get I765 to get I131.
There is no biometrics NOTICE for I131 but it's included because it's a COMBO.
I131 by itself is not a Card.
It's a paper notice with no photo or finger print.
