I have a 2023 HEV EX and my side mirrors fold in manually. I see no reason why non-folding mirrors could not be replaced with folding ones. Have you asked the dealer?
Today cars? Good luck. I have a Sorrento and the controls are on the arm rest. So you would need a wiring diagram to run wires to the powered switch and hook it up to a safe output.
Heck the entire computer system would probably have a cardiac!
