Nope, Nibelungenlied = 1200, Poetic Edda = 1270, Völsunga Saga = second half of 13th century. Mind you, each of these three goes back to oral tradition predating this by centuries, but you can't pinpoint oral tradition, whereas you can date manuscripts somewhat accurately. It's entirely possible that the poet of the Nibelungenlied drew on a younger tradition than the poet of the Völsunga Saga, but he definitely wrote his version down almost a century earlier, and it's equally possible the Nibelungenlied made its way to Scandinavia and was adapted and "Norsified" there. Again, Wagner & contemporaries assumed it was the other way around, and that the Völsunda Saga was the "pure" origin and the Nibelungenlied basically the medievalized updating.
