Not really (as far as the website and the government doesn't collaborate and share information with each other).
AFAIK the EU age verification app works by requesting bunch of digitally signed "proof of age" tokens (openid verifiable credentials) from a government institution and sends (uses up) one when you want to prove your age to a website. The website can check the validity of these tokens without connecting to the government institution.
They are even trying to do some form of blind signature or zero-knowledge proof to have better protections.

Age verification laws are easy to circumvent and they are bad for many other reason though.
