All I can think of are some variations of you trusting a service to validate your id and give you a token that just asserts your id has been validated.
But it’s still not really privacy preserving because it relies on trusting both parties to not collaborate against your privacy. if at some point the id provider decides to start keeping records of what tokens were generated from your id, and the service provider tracking what was consumes with that token, then you can still put it all back together.
