LFP on Shore Power with Inverter/charger?
An inverter/charger requires that you have a battery connected (or some 12v source) so it will supply any 12v to the RV. (Unlike a converter that will do 12v with no battery) Some say not to float...

The idea with lithium is to provide a sufficient 'float' to support any loads that are present without the need to charge the batteries. A voltage of 13.3 - 13.4V will do just that - carry any loads without the batteries being discharged. You could also switch off the charger, but then you would be discharging the batteries, and would need to run them through bulk again sooner.
It depends on how much load of course. Converters have 13.6v as "Normal", which is for when you are using the RV on shore power, and 13.2v is "Storage" for when it is not being used
The answer to the OP seems to be that if you have an inverter/charger on shore power with LFPs, you can set the voltage to 13.6 and be ok.
With a converter and LFPs you do have the choice of isolating the LFPs and running the RV on the converter
