Everything I've seen seems to show the ideal charge voltage for an AGM to be 0.1-0.4V higher than FLA. Toyota/Denso is generally pretty conservative with charging voltages (on the low side, I mean - compare to most US manufacturers), but things have been working just fine for the last 25 years for 3rd gens... why change it? The OEM charge voltage may not be as efficient at charging an AGM, but the float voltage will still be correct for battery health.
That said, an overnight on a trickle charger ever 1-3 months is a good idea. That's what I do on our vehicles, generally.
4Runner: 105A upgraded Denso, sits a week or two regularly but driven long drives when driven
Van: 150A factory alternator, but lots of short trips
Volt: 130A factory DC-DC converter, factory AGM 12V battery
Camry: Tiny Miata battery (U1R), always on the trickle unless being driven
