Non-interleaved vertex buffers DirectX11

Question

If my vertex positions are shared, but my normals and UVs are not (to preserve hard edges and the likes), is it possible to use non-interleaved buffers in DirectX11 to solve

Answer 1

You should stick with interleaved buffers. Any other technique will require some form of indirection to your non-duplicated position buffer, which will cost you performance and cache efficiency.
