I don't know the machine enough to be certain, I believe its a no though, about 4 months ago I tested what I believe was at the time the latest spar firmware and it would still not allow it. I work for Xerox but not on this model, and couldn't find one local, so I had to do testing using one in an office 3000 miles away and get the person to try it with me. Failed.
Ended up enabling SMB1 per the link I gave up above.
Can't hurt to call Xerox though, it may have been resolved in an update.
