That's not possible. If Seattle gets the bye, both LAR and SF are wildcard teams.
The only playoff certainty if I understand it correctly is that GB will be the #7 seed and will play the #2 seed, which is likely to be Philly or the Bears. That and the Rams are a wildcard with final seeding to TBD.
On the playoff chart as of now, the Rams will play at Philly.
