You can sort of opt-out by doing civilian service. This consist of general interest public work (mostly work in retirement homes, but also farmer's aide, museum guardianship, and in this time of pandemic, help doing COVID contact-tracing).
You can't opt out of society in any significant regard, and without being forcefully exposed to very distinct facets of society we close ourselves off to our own little bubbles.
On personal level one does not interact with society, but with other persons. Probably tens or at most hundreds. And one can opt-out of each of such personal interaction (and perhaps find a differend set of persons to interact on personal level). And that is one of the most important personal freedoms.
