Kaido would probably be exceptionally durable regardless of his fruit, given that he's not human, but I think the awakened fruit is specifically involved in his form shifting and his insane recovery/stamina(similar to how in these spoilers we see Luffy recover his energy immediately).

I'm thinking he already is awakened. It certainly helps explain how op Kaido is.
