Yes, you can change the number of steps in configuration. Honestly I haven’t really played with memory on any of my Anduril lights and just leave that as stock. Some versions now have a “hybrid memory” that can be used or not, which I think is what you’re looking at right now…maybe someone can give better information (or you can sift through other threads with a “hybrid memory” search).
These two links might help you with readable flow charts. The reddit one is pretty recent and then there’s a main thread here with Lux’s great original versions.
