how to compete in nsda

Hi so I’m in 9th grade and I want to compete in nsda tournaments but my schools debate team is really bad and they barely compete. So if I wanted to compete in nsda would it be possible for me to get my school to register for it( I could pay for it), and then for me to compete as the only one. Also how hard would it be for my school because I don’t want it to be a big hassle if I’m the only one. I might be able to get more people but idk.
