Can I change M visa to Z visa without leaving China?

Hi all. I came to China in January last year before Covid-19 with my M visa then and later extend as T visa for a few times. Now I found a job and I wanna apply for Z visa now.
So my question is can I do that without having to leave China? Cause I worry that if I leave China, I won't be able to come back in anytime soon. Any answer would be appreciated.
