Itโs the whole point of the sword and what makes it special. Zoro obviously could and straight up was using haki before enma nobody is saying otherwise. Legit all it does is force more haki out than normal with it being zoroโs job to control how much that is. Either completely stopping it from forcing haki out or the opposite and letting it force out as much as possible
No one gets mad that sandai was capable of cutting more than what zoro wanted
	
	
		
		
	
	
Or that Shusui was doing more damage than he wanted
	
	
		
		
	
	
Itโs literally the same situation with enma I just being trickier to master
