J'y ai également trouvé la réponse à ta question. Si tu achètes la version digitale, il ne sera pas possible d'avoir une version physique.
Et si tu prends le pass digital, ils conseillent d'imprimer la version pdf au cas où il faudrait l'afficher derrière le pare-brise.

Mobile app; tap Reservations button to access digital pass
Download the pass to your phone, using your Google Wallet or Apple Wallet
Print a PDF version, and/or
Bring the physical pass (if available)
Visiting unstaffed locations. Many unstaffed locations require that you display a pass from your vehicle. Be prepared by bringing either your physical pass or printing the PDF format of your pass.
With the Digital Non-Resident Annual Pass, can I also get a physical copy?
No, if you purchase the Digital Non-Resident Annual Pass you cannot add on a physical version.
If you want a physical version of the Non-Resident Annual Pass, do not purchase the Digital Pass now. Instead, wait to purchase your pass in person when you visit a federal site. After you have the physical pass in hand you can connect it to a Recreation.gov account to add a digital version.
