Unfortunately, no. You can change the selection color using the view theme,
but cannot disable it. Internally vtkGraphLayoutView uses vtkApplyColors,
which does not appear to have that capability:

http://www.vtk.org/doc/nightly/html/classvtkApplyColors.html

An option could be to add a flag to vtkApplyColors to turn off selection
coloring, then exposing that parameter to vtkGraphLayoutView.
