The JSON which allows you to define the Dijkstra configuration includes a 'TransportLink' property which optionally can be added to force the network path to include or exclude interfaces from another transport function in the service definition.

Contains:

• Function: The other transport function of which the interfaces should be
  included or excluded.
• Option: Should be set to Exclude or Include, depending on whether
  you want the interfaces to be excluded or included.
• Strictly: If set to false, all paths will be displayed. In that case, depending
  on the Option configuration, either all the paths that exclude the interfaces used in the linked path or all the paths that include those interfaces will be shown with highest priority.
