Sure you can. Just beat the one team in the championship that beat you in conference championship. The NC and conference championship have nothing to do with each other. They are separate playoffs. Of course conference championship mean something, otherwise there would be no conferences. They just don't have anything to do with the NC. Do you think the PAC 12 champion, 10-4 Utah, deserves to be in the playoffs? Do you think the PAC-12 title doesn't mean anything the them? of course it does, however, they are not as good as the second best team in the SEC. Same is true for every other conference in the country. Why is it you want to penalize the second best team in the country just because they play in the toughest conference in the country by far, but you want to reward non competitive teams who win a weak conference championship? That is antithetical to competitive sports and makes no sense whatsoever.
