Webview2 with internetexplorer.application with sitelist.xml

Hi,
I'm trying to use both webview2 and internetexplorer.application object (https://docs.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/platform-apis/aa752084(v=vs.85)) because I need to manage also web sites that are not supporting internetexplorer .
I know that today is not available the iemode inside Webview2. The problem is that with the sitelist.xml configured i cannot manage the switch between the two browsers. From internetexplorer object i cannot catch the event of a link that should open in Msedge: no beforenavigate2 event is launched. There is a way to tell internetexplorer.application object to not switch automatically to Edge?
I need a way to switch manually from internetexplorer to webview2 without passing to MSEdge.
Sitelist is needed to manage the pages in iemode outside my application.

Thanks in advance for you help
Best regards
