IMO, it is likely (51%+) that the image is that of a Confederate enlistee of 1861. The upper garment is of a style referred to as a "battle shirt", such being quite common during the spring and summer of 1861, filling the gap prior to units being fully outfitted by their respective states. In particular, the two large patch pockets and the tape piping in a contrasting color can be seen in a number of southern boys' images. In fact, such very early-war blouses can be found in photos identifiable to men of quite a few southern states, from VA and NC to LA and MS.
The man's forage cap is a bit unusual in having a strong forward pitch and a notably small circular disc in the crown. Again, however, virtually matching headgear can be seen in other early Confederate studio portraits.
Overall, there is nothing about the image that conflicts with the NC Confederate association.
