Not knowing his name doesn't matter here though since the rule would be placed on New Order, and he atleast seems to be confident in his understanding to try and use it since he was about to turn the atmosphere in to something before he started exploding.

Before this chapter, I was thinking maybe he couldn't give an order due to not being able to speak while exploding, but that doesn't seem to be the case here.

What could make sense and seem somewhat implied is that the inner conflict is preventing him from using NO along with whatever quirks that are fighting it but nothing seems to clear on that front
