No. We do not recommend using nails or nailers, but using screws when installing composite decking. The material is very dense and getting nails to penetrate to a proper depth without bending can be a challenge. We recommend that all holes be predrilled to help reduce mushrooming, and avoid splitting. When using nails or nailers, the concern is that the ends would not be predrilled and possibly lead to cracking and splitting.
