That’s not a feature of Teams. I know Microsoft had been testing processing eyes so that it looks like you’re straight into the camera, but no there’s no reliable way to do that based on who’s feed you’re watching.
Some Sony still cameras have sometimes done funny things with the eyes. A friend bought one in Japan which made the eyes of any subject larger. I can’t seem to find anything online about it, but it was very strange before you realised.
Magnifying eyes is common on Purikura machine in Japan. Some cameras including smartphones implement similar feature. I believe all camera have plain shoot mode.
