Not to my knowledge.

You should be able to compute the number of lines you need in each
dimension based on the frustum available from
vtkCamera::GetFrustumPlanes(...). Or you could do something fancy like
place a screen-filling plane source with a custom shader that computes grid
lines based on the interpolated coordinates in the fragment shader.
