Postman Proxy Environment Variable to toggle proxy on and off during collection run

Hello All,

I created a postman collection chain in my enterprise environment having 3 API calls in it. While the first two require the proxy to be on, the last one does not want the proxy. When i run the collection using collection runner, the first two pass as I keep the proxy setting on before running it. The third one fails in the collection run as the proxy needs to be switched off. Is there any postman environment variable through which I can toggle the proxy on and off.

Look forward to hearing from you.
