Once the LFP is charged (to whatever desired user acceptable level - a LFP thingy...) with an existing multi-stage converter-charger, all you need to do is shut off the converter-charger at the breaker panel (or solar charge controller)...Another option (if so inclined...) would be to install a disconnect switch at the battery terminal, and keep the onboard converter-charger active, Presto, problems solved...

I was only making a point that most converters (or all of them?) don't automatically do what is the best for LFP. And neither do many solar controllers - though in a decent controller you are normally able to set a custom profile for LFP.
Yes, you could shut off the charger when voltage hits 14.x. By the same token I could eliminate solar controller altogether and charge the battery directly from solar panel, keeping an eye on it and disconnecting when it hits Absorb. (In fact, did this for a month when my controller died - even though it was 24V panel with 12V battery). You just have to watch it. Having an equipment doing watching and disconnecting would've been much better :)
