I discovered how to do it. There is a control app, the one you use to turn on your heat or ac for your front seats. On that app in the center of the three columns there is a button to deploy your running boards. You can only do this when the truck is in Neutral or Park. You can't deploy them when you are in Drive or Reverse. If you deploy them in while in Neutral when you shift to Park they will reset back to normal mode since to get to Park you had to go through Reverse first. If you deploy while in Park they will stay deployed even after you turn off the your truck and open and close the door. They will revert back to default mode once you restart your truck and put it in either Reverse or Drive. You can use them to help prevent door dings. If you have air suspension you can also raise your truck one level which raises the running boards along with the truck. Should give you a little extra protection for people who don't pay attention when they open their doors. Tried to see if I could raise the truck to the highest position but it won't let me do that, I suspect the truck needs to be in 4WL for that to work.
