Anyone know the trick to force the game to use the VFX for a specific face mod

I remember reading something a while back that had a trick to control which face mod's VFX gets implemented. Anyone know what that was? Patches for VFX won't help because the mod isn't supported by that one yet, but the mod does have native VFX support if I don't have any other face mods installed.

I know it's not load order.
