Hack or Mod for enabling a My Room mode while charging Prime

I know of the hack of pressing the pre airconditioning button on the keyfob. But the AC only lasts like 10 minutes.

On the RAV4 Prime, they have a dedicated room mode for the Car while it's charging, the AC can be used.

Is there a way to mod the car to do this?? Maybe from the OBD port to extend the Pre AC time?

Thanks, we are all rule breakers here I'm sure
