I think that’s why the DRV might step in and force a freelancer to pay into the social security system if they have a single client. If I recall it also applies to foreign clients, but I’m not 100% sure how far it extends. It’s definitely easier to bypass the DRV if your client is not German, but not entirely waterproof as I recall.
