You can use the pfuTraverser to write a function that sets the
wireframe mode off all the geosets that are below a certain node.
Or you can set pre and post draw call backs to the wanted DCS's and
put in these functions call to set and override the wireframe mode.

int preDrawWireframe(pfTraverser* trav, void* data)
{
    pfEnable(PFEN_WIREFRAME);
    pfOverride(PFSTATE_ENWIREFRAME, 1);
    return PFTRAV_CONT;
}

int postDrawWireframe(pfTraverser* trav, void* data)
{
    pfOverride(PFSTATE_ENWIREFRAME, 0);
    pfDisable(PFEN_WIREFRAME);
    return PFTRAV_CONT;
}
