Hi,
Sorry I don't have any help for this one (especially since the icon is within the LCD).
I know that when I changed mine (I have a GD), if you use the factory scan tool (or Chinese knock-off), there is an option in the instrumentation panel settings for the instrument cluster to be reprogrammed to match the options which are available for your car (but doesn't alter mileage). If you can find someone who has the tool + software installed (I ended up getting mine from Aliexpress), you maybe able to see if that helps. Or you may have a friendly dealer / garage with the hardware and they maybe able to try it for you.
I know for someone who replaced their GD display, they had an issue with the electronic park brake, and I think they removed the LED on the PCB itself. I never had that option light show up (even before I reprogrammed the settings on the display), but that LED never displayed for me.
