If seen some that have an agm setting you can select but my stock one doesn't have this feature

The diffidence between flooded battery and AGM optimum charging profile is 0.1 to 0.2 volts higher on the absorption stage. AGM batteries have little resistance thus can except higher charge voltages without out-gassing. This higher voltage materially shortens the time of the adsorption stage
There is a problem if AGM batteries are charged too fast in the bulk stage. Because of the paste on the mats the ions can move only so fast between the plates The movement needs to happen so the ions can be reunited to form water. The max recharge current recommended is 10 to 13% of the battery banks amp-hour rating. So for a 200 amp-hour battery bank the max current should be between 20 to 26 amps. Any more current risk the battery producing excess hydrogen and out-gassing.
The chemistry is the same but the limitations are different.
