Sounds like you have done and tried most things to make it work. The drivers and setting in Optimus will enable Lumion to work, if the card itself is capable of running Lumion.
The specs and Passmark for the card are low, with Passmark 1297 which is 25% below the recommended minimum hardware for simple scenes.
Either the card itself is incapable for some specific hardware reason, or it's just not capable, even though some lessor GPU's do run Lumion, this is an M series card. With that version I don't think there is any way to overclock to get more performance from the card.
Did v3.2.1 work in any way?
You can run the DXDiag report and post here, Windows --> Run -->DXDiag.
Unfortunately I suspect if you have not got things going with what you have done then that's it, it's not going to work with Lumion.
Equally important is that even if you got it working, the user is not going to be able to do much with it, and will most likely constantly hit issues, extreme limitations on what can be put in the scene etc.
Suggest the need to consider alternative hardware.
