GiroDisc is closed on Fridays. Still waiting for some other shops confirm if in fact they have a solution for my need.

Some more "cool trivia information": I just got done talking to a very large and reputable Porsche dealership in USA and the person told me that you can in fact "easily" swap out PCCB disc for Porsche steel (Turbo) discs,*BUT THIS CAN ONLY BE DONE IF YOU HAVE 390MM PCCBs.

The truck I'm looking at has options 1LX (Front brake discs for min. 20" wheels, yellow calipers (PCCB)) and 2EH (Rear brake discs for min. 19" wheels, yellow calipers (PCCB)) which means that the front discs are 410mm, not 390mm. PCCB 390mm front discs use the same caliper as the 390mm steel discs. Cayennes equipped with options 1LX and 2EH have different calipers from all other models. If you want to change to steel discs, then you need to basically change calipers, rotors, pads, knuckles and a whole other series of parts.*

I'm not 100% sure, but I believe that these are the following correct sizes (front/rear in mm): PCCB: 410/370 ; PCCB 390/358; Steel (Turbo): 390/358.

@911boost: did share this on Rennlist too...
