Clarity doesn't have a feature like that. What I do is when I am about five minutes from home I press the climate button then I press the A/C Off button to turn off the A/C compressor. Note that the A/C Off button must be highlighted otherwise A/C will still be on.
After a couple of minutes as the cabin temperature starts rising I start turning the fan up. By the time I arrive home I have the fan running full blast, both to keep the cabin cool and also to try and get maximum drying. Just before I turn off the car I press the AUTO button to turn A/C back on then I immediately turn off the car. The reason that I turn A/C back on is so that the next time I start the car A/C will already be running. If I forget to turn on A/C before turning off the car, then the next time I start the car the fan will be blowing full blast which is somewhat disconcerting when you aren't expecting it.
I read somewhere that in order to really dry things out you need to run the fan for about fifteen minutes. But no way I am going to drive for fifteen minutes without A/C on a hot day. I figure five minutes of drying at least helps somewhat.
One person said that if A/C is turned off in the climate screen when you turn off the car, then if you later use preconditioning it will only run the fan. I wish that were true because then what I could do is when I got home I could use the fob to start remote climate and it would run fan only for thirty minutes. Which would probably be overkill but at least it would be dry, and at minimal battery usage since it would not be running the compressor. But when I tried this it didn't work, even though A/C was highlight as Off in the climate screen when I turned off the car, when I ran remote climate I could tell that the compressor was running because cold air was coming out of the vents.
In your case since your wife drives the car, I would guess there is zero chance of getting her to shut off A/C for any length of time. So I would say you probably will need to stock up on Lysol.
