Need help with MPPT Controller charge settings for 22.4v (7S1P) LifePO4 Battery

I have this 22.4v (7S1P) LifePO4 battery taken from a 1024Wh broken portable power station. The main control board on the power station no longer works, but the battery itself is fine. The battery does have a built in BMS that I can see is attached to the battery pack. I don't have a user manual for the battery (for suggested settings) as the battery was part of a power station.

I have this Renogy Rover MPPT Charge Controller and it has a user setting for me to custom configure the charge settings - and it has Bulk, Constant, and Float stages.

What would be safe charge settings (Bulk, Constant, and Float) for this 22.4v battery? Do I just go with 25.6v for all 3? Thanks!
