Is changing the graphics to such extent bannable?

That might be your opinion, but that's not how things work.

The Nvidia control panel has many settings that the game doesn't. By your logic, those should be bannable, and that is why that's not how they work. Nvidia Inspector doesn't modify any game files, it's also not something used to give a specific advantage in most games. Some games it could, but based on appearance, this isn't one of those.
