Ford engineers are working on the software that will implement PaaK on the early build trucks. They don't have a solution to roll out yet, so I recommend you be patient. Neither your dealer nor the Ford help line can do anything to get PaaK on your car at this time.
I'm in the same boat. I'd love to be able to ditch this huge fob I have to carry around. I've been spoiled by PaaK in my Mach E.
