Lowest fan speed - still too fast/LOUD! Any hacks to fix?

Does anyone have a suggestion or hack as to getting the fan speed lower? When manually set to its lowest setting (1) the fan speed is still too high and LOUD. Such a quiet vehicle, with the most noise coming not from the wind or tires, but the damn HVAC fan! Besides shutting the HVAC system off, is there a hack to get the fan speed lower?

Yeah, I ended up taking it off Auto so it would stop being so loud.
I found stopping the rear climate completely also helped the system be quieter when you only have front passengers.

Auto - fan speed too fast even when the ambient temp is similar to the temp setting.
Manual - lowest setting (1) isn't "low" like one would expect.

Perhaps a software issue with my particular vehicle. I'll need to ask next oil change.

Be sure that the front and rear are synced.

That was the answer!
Coming from a Land Rover Defender, I was able to run the rear-most A/C fan on high to keep the dog cool, while running the rest of the cabin on auto to a temp setting. I erroneously assumed that would be the same in the GC, but with the rear seat fan controls set to high, the fan in the front seat area would still run high even when at the lowest (1) setting in manual.
Most of the year here in Arizona, even with heavy tint on the windows and UV block on the windshield, the fan runs high tying to keep things cool - but during our mild winters, I will enjoy the quiet comfort of the Summit Reserve.

Can't thank you enough Boggswade.
