DLC trophies boostable in private matches?

[NickMeister77]

It has been a while since I played Battlefront, even though I purchased the season pass and I only got back on this weekend for the 4X xp weekend, and I was thinking about going for the DLC trophies with a friend and we were just wondering, is it possible to obtain DLC trophies in private matches so we can boost them? I would try it out now but we don't have enough friends on Battlefront so if it's confirmed that it is possible, we will probably make a boosting session by the time the Rogue One DLC will come out. Thanks.
