I read that as "NVIDIA encourages you to be ethical and prohibits breaking the law. That doesn't seem so bad to me. What is bad, however, is section 2.1.

> 2.1 ... If You institute ... litigation against any entity ... alleging that the Model or a Derivative Model constitutes direct or contributory copyright or patent infringement, then any licenses granted to You under this Agreement for that Model or Derivative Model will terminate...

If you sue or file a copyright claim that the model violates copyright, you lose your license to use the model. That's a really weird restriction, I'm not sure what the point is.
