I would be pretty surprised if they traded Nunez. He won't be a free agent until after the 2024 season.
Obviously everybody is available at the right price, but I don't expect the Orioles to get an offer that blows them away for a DH.
I do think he's a legitimately good glove and that's a valid resource to provide pitchers. I'd value that contribution more it it were Akin, Kremer, Baumann but I suppose three starts in there's even a chance he could help Cobb follow in Cashner's footsteps.
To an extent he's a barometer for the Golden Age of shortstops. He may have been a minor star in Belanger's time.
I remember doing the exercise when we got him - it's something like 25 clubs that have about a 3-win starter there, and along with trailing Gavin Lux, Royce Lewis and a few others, this summer he's probably around MLB's 28th-30th best SS give or take a few places either way.
Come to think of it - we're heading into the high leverage time where the health or lack thereof of the Top 20 might result in something slightly interesting for him becoming possible. And if not, he is a fair bridge to the '22 Lindor Cohort.
