Question... Can I use a universal Givi mount and just drill holes and mount it to the black cover on the rear of my NT???
That plastic cover is pretty thin, I'd be a bit worried about it cracking, at the covers mounting points, or at the holes you drilled, and popping off with my trunk... If you go that route I would definitely suggest longer bolts and putting some Big fender washers on the bolts that secure the cover to the bike...
