There is a 12V BMS that has separate settings for flooded lead acid, AGM, etc as they each have slightly different charge characteristics, giving slightly different voltages when fully charged. They've had to reset it each time they've replaced my 12V battery.
Folks that put optimas in can run into this awesome behavior where the car will see the normal fully charged voltage of the battery and treat it as if it's dangerously low.
You'll see this when you switch off the car but don't open the door. The fans and console will normally stay on for 30 minutes but it will almost immediately give a message about preserving the battery and cut off. I get this frequently even with the Ford standard AGM battery.
On the gas version, you can pull the 12V sensor plug off but on our EVs it will just refuse to work like that.
Feel free to mess around, just letting you know folks have tried exactly what you've been considering and it's not as simple as swapping them out.
In a perfect world we could find BMS commands that would set the proper float voltage values and low voltage cut off for any given battery but I'm not holding my breath.
If you have a copy of the service manual that's floating around, there's a little more detail in "414-00 Charging System - General Information". While it does mention a 12V battery management system it doesn't go into further detail. I believe the "BMS" they always check when my AGM droops is the Battery Monitoring Sensor that reads into the BCM.
