Do I need to change out my converter?

I just recently did some research on my inverter/converter and one of the things I found is that there is a setting to set it for wet cell, AGM, or a third type which I forget right now. Mine (like I'm sure yours does too) charges both the chassis and the house batteries. But there was no way to change the setting independently for the two battery banks. What that tells me is if I were to change to AGM batteries for the house, I'd also have to change the Chassis batteries to AGM.
