It requires full conversion to disable night vision completely, but if you make the area the player walks in illuminated with a light value above the treshold that triggers night vision, it wont happen. Thus do this thing I used in my 24 hour amnesia map:

Spoiler below!

make sure the player can actually navigate in there, I did that terribly and people had serious trouble getting past this thing. But yeah, it doesnt illuminate the walls but only the player so night vision wont trigger...
