If I try to change song styles while a song style is playing, the one that is playing shuts off. I was wondering if I could avoid this by locking the playing style, but no.

On the other hand, you can have up to about 28 band styles per song style. These can be mains, intros, endings, fills, etc, without limitation. You can mix band styles across song styles before starting autoaccompaniment. Also, you can make new song styles with any combination of band styles. So there is great flexibility as long as you know what band styles (variations) you want before you start autoaccompaniment.

However, this is certainly a let down from my Yamaha PSR-8000 which allows me to switch styles on the fly.
