150/100 MPPT settings for 48v Nissan/lipo/nmc

I have 4380W of panels; a Victron 150/100 MPPT; 2 banks of 11 Nissan cells each 80Ah = 160Ah. I replaced an EpEver 60 that went bad which I had set at 58v for the charge voltages - absorbtion, float and equalization (as I recall). New Victron mppt sets me at absorb 56.8v, float 54v, and disabled equaliz for lifepo4 bats(only choice for preprogrammed). My BMS's (one on each of the 2 banks), JBD-SP15s020, I've set to a presetting called "light polymer" which is 58.7999 for pack overvoltage. Can I/should I edit MPPT preset to higher and closer to BMS settings?

You could do this, but the amount of extra charge you will get into the cells will be minimal. Also the lower voltage wil extend the life of the cells slightly, so I don't think it would be worth the effort.
