If you're talking about playing against a bot operated by an online casino site, much like when you're playing blackjack it's of course possible. I've seen and played online poker against a provably fair bot more than once.

If we're talking about playing other people it's impossible, because the provably fair system only verifies seeds by making sure that the house "roll" stays anonymous to both sides and isn't changed until the player sees it on his screen.
In a poker game people don't roll, they choose cards themselves. The only way a casino could cheat in a pvp poker game is by watching your hand and revealing it to other players who would be planted casino employees.
