How to stay out of S

Accidentally got into S rank for the first time ever last season. At first it didn’t seem too different from A but eventually I got down to S -500s. Didn’t realize you don’t derank back down to A/B ranks once you reach S. With the new season I’m back at A+, but I’d rather stay out of S for a more chill experience and also to try to learn new weapon types I’m not as familiar with. I don’t feel good about the idea of throwing games. Anything else I can do besides avoiding series, solo queuing in open, and switching weapon types when I get too close to the rank up?
