I know this setting. Maybe I described this wrong in the first post, but I want disable only billing address (not real name) for physical products. And I cannot do this. In post-Soviet countries there is no 'biling address' concept. We have to provide only shipping address when purchasing something in internet stores. And billing address is really annoying us. I cannot understand why there is one setting both for real name and billing address. Real name is required by almost all stores, but billing address is not.
