Yes, you can make the switch. Just apply for the SEN Officer role and go for the interview. But think carefully first before you make the switch. The $$ is a significant decrease. No connect plan, and pay range is lesser. The work is also not necessarily simpler. You may be managing lesser students compared to the teacher in the classroom but the students you manage as a SEN Officer are those with the highest needs. And most of the time, you are the only 1 or 2 SEN Officer in the school. Unfortunately most schools are still not inclusive in nature so a lot of SEN-related work and students will be thrown to the SEN Officer to handle alone.
