you could also try to decode and use the CarPlay simulator that apple provides and get it running on a rpi because I am guessing there is some way for it to conect to your phone with out any complications but I don’t know how to get it working

I looked into this, but unfortunately this does not work because the new CarPlay Simulator only runs on Macs equipped with a T2 chip, and the simulator uses Apple's BAA authentication based on said chip in place of the MFi coprocessor.

I'm not sure: I assume you're talking about the internal MFi developer site? I'm not aware of any public documentation on the normal Apple Developer portal.

I assume the digital MFi is issuing individual certificates and placing them in the secure element of the microcontroller?

Not really useful to us if so, as I assume they work closely with the vendors to implement that, and the secure element is designed such that it is usually impossible to extract the key without side-channels or attacks that would be complex to pull off (and that specific certificate could just be revoked once it became public anyway).
