Pivy (Python wrappers to Coin3d) is not needed to build FreeCAD or to start it, but it is needed as a runtime dependency by the Draft Workbench. If you are not going to use this workbench, you won't need Pivy. However, do notice that the Draft Workbench is used internally by other workbenches, like Arch and BIM, so Pivy needs to be installed to use these workbenches as well.
