We don't know whether or not Putin will listen to such warnings. But, given the intensity of Russian nationalism, and how little they are held to account for their policies abroad, Putin will be fearful of losing his people's support. And this might persuade him to stop his aggression.

I would have requested him that rather than going to deadlock situation - please go for dialogue. The war is a curse and it kills people on both sides. So let's make a wise decision of not starting war.
