You'd have to test if this is the case now, with whatever charger you buy, but in years past the difference between a LiFePO4 charger and a Li-Ion charger was that the LFP charger did not shut off it's output voltage once current dropped below a certain point, while the LI did.
If you look around Dnmun's posts there are a few that detail some of this, including showing what board to remove from certain brands/models of LI charger to turn them into LFP chargers.
Other than that, the chargers work the same basic way.
FWIW, many decent chargers have adjustments inside for at least the max voltage, and some also have a termination current adjustment (point at which they turn off when current drops below that), as well as a max charge current adjustment.
Note that if you intend to manually terminate charge, or have a separate device to do this (BMS, etc), and don't want the charger to turn off it's output, you can use LED PSUs like the Meanwell HLG (and ELG) series as chargers. I use the MW HLG-600H-54A to charge my EIG NMC C020 14s2p packs for the SB Cruiser trike; this version has an adjustment pot for current and for voltage.
They are also waterproof and vibrationproof, being completely sealed and potted. (mine is bolted to the bottom of the trike and has been submerged at least twice in flash floods as I rode home from work; it's been working for years without problems, and I got it well-used rather than new). (I also have a 12v MW in the 150H series up on a pole in the backyard running an LED panel; it's been there for at least a couple of years in the sun and rain and heat and cold and still works).
Just remember...they don't turn off (which a proper charger would, with the exception of chargers specifically designed not to for balancing or other reasons) when current drops below some point, so it's up to your battery's BMS or other device you install to do that.
The Cycle Satiator is also a good charger...thoroughly programmable, but it isn't cheap and only comes in a 300W size (three voltage/current combination variations, though).
