No. People like Karma and Kayano saw Nagisa take off the tag from Bitch-sensei's shirt without Bitch-sensei noticing, but they didn't know how he did it; much less know it was skills learned from the God of Death.

Futhermore, Nagisa only told his skills to Korosensei and nobody was allowed to eavesdrop during the conversation because it was meant to be a private conversation about the student's future.

Plus, since Bitch-sensei didn't notice Nagisa taking off her shirt's tag, she shouldn't have known about his God of Death skills.
