Can someone pls confirm if negative prompts can be used in Illustrator's desktop generativr AI tool?

The generative pattern tool tool an illustrator (desktop) is seemingly impossible to tame... At least without negative prompts. 

I know Adobe did away with negative prompts in the Firefly web app months back, but there doesn't seem to be a definitive answer as to whether Illustrator's generative tools rolled out with or without this feature.  

I recall reading a suggestion for using negative prompts in Illustrator a few months back, but now I can't find it. 

Can anyone please confirm? And if so, how exactly are negative prompts triggered/formatted?
