Maybe so, but as Pyrrha said, Aura is a conduit for every tool and equipment of theirs (thus they could conceivably channel it through food, among other things)

Maybe it takes more effort to form an actual shield or something, like Ren did, but it doesn't seem out-of-the-question to generally use it to block damage from hits (though not the recoil)
