I'm not sure that would work all that well to be honest.
Seems to me, the whole reason ID cards have photos on is because they get lost/stolen/borrowed all the time.
Even if the government had the inclination to run a big national IT project so I could use zero knowledge proofs to verify my age for pornhub by scanning my driving license NFC chip, they'd still end up needing a webcam face check to make sure I wasn't some kid using dad's driving license. At which point the privacy angle becomes a joke anyway.
