This does not affect WebView2, however, so Zoom runs well with MS Edge disabled. One could open services.msc and manually disable the three critical update services, as shown below, and set GPO to disable Edge browser itself, but a third-party tool such as Sordum's Edge Blocker makes it convenient to turn MS Edge and it's update services on or of with a single click. The easiest and safest thing to do with MS Edge, if it's not wanted (nor its pseudopodia to Bing and other MS 'services'), is to disable it, and to disable the update mechanism. If you remove WebView2, you will disable Zoom and other applications dependent on it. Third-party applications such as Zoom use Microsoft Edge WebView2 (I've observed Zoom running as many as eight EdgeWebview2 processes!).
