I have tried this MPPT on LFP just for a couple of days to charge some large cells, just to experiment I didn't change any settings ( I should, will later ) from what I had running the FLA battery in the shed.
I did find the charge controller behave differently when charging the LFP batteries, it stayed in mppt mode then cut power for a moment then continued charging and repeating, this went on most of the day, it eventually went into absorb mode most of the next day so I should change a few settings to get it right
The voltage on the FLA batteries used to rise fast and charge in absorb very quick, the LFP battery voltage didn't move, just barley, so might be some voltage differential setting.
When I get the rest of the system built I will set it up better.
Regardless of battery chemistry we stay within the manufactures specifications, a lot of people have there own personal preferences within those margins.
