I honestly don't know, they are not out there campaigning for one. Their current position seems to be that either way it wouldn't be their fault if there was one: https://www.irishtimes.com/news/politics/dup-doubles-down-on-foster-s-claim-that-ni-never-had-hard-border-1.3759796 https://www.irishtimes.com/news/politics/dup-doubles-down-on... They certainly don't seem to want a hard border with RoI, but they will sooner chop an arm off than accept a hard border between NI and the rest of the UK, so given the choice I think they'd take the former. They're the Democratic Unionist Party, keeping NI an integrated part of the UK is literally their entire reason for existing.
