Dungeon Meshi might fit that criteria. It's a completed story only about 100 chapters. It's a little more fantasy slice of life but with a LOT of action. Virtually zero romance. Not sure if it's quite what you're looking for tho.
Not really adventure (sorry to be that person ) but Delivery Knight was an incredible read also with no romance. That's kinda hard to come by so I wantted to recommend it. Its dystopian action, so probably definitely not what you're looking for.
Hopefully someone else has more relevant recs
I am lately interested in adventure trope can someone recommend good ones with minimum romance
