This request started appearing since Edge Canary version 133.0.3037.0 in our automated tests ran against pre-release Edge channels. It's not a feature that is enabled in WebView2 and it is sensitive from a privacy perspective. Can this be removed?
Here are previous tickets raised to disable network requests:

Importance
Blocking. My app's basic functions are not working due to this issue.

Repro steps
Start Fiddler or a similar MITM proxy
Run an app that uses WebView2 with the Canary or Dev runtime version. If re-running an existing app make sure to delete the bin folder so the webview2 profile is deleted.
As soon as the app starts and a navigation request is made a call will be made to http://edge.microsoft.com/browsernetworktime/time/1/current?cup2key=[...]
Repros in Edge Browser
