Which anime is that where the boy discovers he can shapeshift in a white tiger already? Bungou Stray Dogs or something? Is that supposed to be similar here?
There is nothing in lore right now that supports shapeshifting as far as I know, except this handful of things:
1) Transforming into a dragon. This is specifically tied to ishgardians whose ancestors share a bit of the blood of Great Wyrms. If they drink dragon blood, they can transform into dragons more or less permanently as far as I'm aware.
2) Transforming into a voidsent. This is where you get tainted by Voidsent shit and your flesh gets slowly corrupted to the point of transforming yourself into one of them. You slowly lose your mind and your aether slowly dries and twists into a husk driven by its lust for aether. This is different from being possessed by a voidsent without a physical form that is using your body as its vessel.
3) Turning into a primal avatar, like Ysaile or Thordan for example. This is totally reversible, especially when you run out of crystals, as you may know that primals must eat a constant, colossal amount of crystals to sustain themselves or else they wither. The more powerful they are, the more colossal that amount is. Alternatively, they can also feed directly from the planet aether (cf Alexander), or artificial aetherochemical generators/tanks (xf Bahamut and the Warring Triad).
