Take 2, stock firmware 2017 Lariat. I'm guessing the date at the bottom of the windowsticker is the build date; 09/08/2017

There is no going back. If you have a 3.0 system, you can never go back. If you are on 3.2 or higher, you can go back.
A Ford APIM is a Ford APIM, doesn’t matter what vehicle. Sync 2 retro fits, 3.0 stock systems and Ford pass systems have successfully been upgraded. If you have a hardware function, that hardware function will still work.

I think it is possible, but I also definitely think this is the wrong thread for your topic.
You should jump over to the other thread and maybe begin exploring what kind of TCU Ford stuffed in your vehicle and how it is wired. You might need a TCU retrofit. To my knowledge, nobody on the planet has accomplished what you are asking, but I think it should be possible.

If you don't mind, please tell me where in the diagram it mentions anything about downgrading?
