Modify HVAC Fan Speed?

[FirstFord]

'22 502A Lariat, equipped with "full auto" HVAC (but I run in "manual" mode 90% of the time): Can the HVAC fan speed (RPM) be modified, possibly through FORScan, or any other method? On my truck, with the fan on the lowest setting ("1"), it is still blowing an awful lot of air - too much air in my judgement. I find myself constantly trying to turn the fan down, but it is already at its lowest setting.

Maybe it's just my truck but I swear the update from the HVAC TSB for the condenser freezing changed the fan speeds, before fan speed 1 for me was great once the cabin reached my desired temp, now it feels like the old 3 and it seem variable, sometimes it feels like the old fan speed, other times its way too much air.

I have a 22 xlt rc 5.0 and mine does same thing. You could be on 1 then it just to blow a ton of air. And why if you use the remote start once you get in and turn the key does the ac have to quit blowing for like at least 1 minute or so.

Our 22 Bronco Wildtrak and 24 F150 do this. It’ll randomly blow 2-3 speeds faster. I have to turn it off and back on for it to make it go back to the normal speed. Never inquired or asked about it.
