Several people did it already, Era quit her job to become a full time vtuber, Rio too, not sure about Shizurin but it's likely, Kerin just quit his job as well, Mirei wanted to quit her job after the incident where some students found she's a youtuber, and since she hasn't twitted about work in a while and is travelling from place to place it's likely she did quit already.
But you don't become a NEET by becoming a full time vtuber, it just becomes your job.
