There is not.

Techically it is possible. The question you need to ask is how useful
would it be. NURBS are vary handy in modelling programs for defining
and manipulating complex surfaces. Since POV-Ray is not a modelling
program there will be no way for you to directly change a NURBS surface
and it's usefulness becomes dubious. Triangles can and do accurately
represent the surfaces that NURBS do. Most any capable program that
can model NURBS surfaces can also exported to a format that can be
converted to a triangle based mesh.
