Collisional ring?

No, not a collisional. There’s no closed ring, no symmetry, no clumps or knots with the distinctive blue color.
An interaction or merger, perhaps?

I agree to disagree then… looked like a partial collisional ring there and the neighbouring elliptical there

There’s an interesting faint polar-ring galaxy right next door to your collisional ring

nice find

I included it in the NPA, three other candidates you’ve posted using the search “p.r”

Agree its not a collisional ring. Interaction wasn’t full-on enough. However, its worth noting that collisional rings dont have to be symmetrical (in fact, very few are).

You’re right. Many of them are very not-symmetrical.
Sorry; brain wasn’t functioning.
