Not currently. They supposedly announced that they were changing over, though. Which looks more and more like PIN will probably be lower priority than signature on Chase cards.
Maybe some don't even know about this? And when they accept the default, it enables signature. And then they're surprised when a signature pops out, don't know what to do with it, and void the transaction.
Actually, it's against the Visa/MC merchant agreement to disable signature verification, so the ability to disable it in the terminal software might not even be there.
