Collecting Coverage using Vmanager

Your question is somewhat ambiguous, because toggle coverage is automatically collected for rising and falling edges, and you haven't clarified exactly what you currently observer and what you would like to observe.

You can configure coverage instrumentation using a coverage control file at elaboration time, have a look at the docs https://support.cadence.com/apex/techpubDocViewerPage?xmlName=iccugn.xml&title=Integrated%20Coverage%20User%20Guide%20--%20Table%20of%20Contents&hash=&c_version=24.03&path=iccugn/iccugn24.03/iccugnTOC.html in particular the section "Understanding Toggle Coverage".

But to be honest, I would be inclined to simply exclude this signal from toggle coverage, as it doesn't appear to provide any value in terms of telling you what has been verified. Block coverage would already tell you if you've execute the if-true and if-else branches.
