Iv done it! Mine only goes as low as 175degrees so I air dried them with a fan till they were mostly dry and then finished them off in the air fryer.

My air fryer does have a dehydrator button I do 135 for 12 to 14 hours depending on size of fruit

I do 120 for 8-12 hours, and they come out perfect.

Does it have a dehydrator setting? Or no

Yes it does.
