I don't have experience with peerjs but with "vanilla" WebRTC you can pass constraints to getUserMedia for example:

To require the rear camera, use: { audio: true, video: { facingMode: { exact: "environment" } } }

https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia

This documentation is for Firefox, but on the bottom of the page it says:

Chrome uses an outdated constraint syntax, but the syntax described here is available through the adapter.js polyfill.
