Quite possibly not. He can be DFA'ed to open a roster spot, assuming the FO sees it that way. In that case, they are on the hook for his remaining salary anyway. And so, it is no cost to them to instead offer to cover his salary if there are multiple candidate teams who would sign him for major league minimum after he's a free agent. So any possible trade value IMO will come from this approach, via a very, very minor bidding war while he can still be traded.
