Disable Activity Map on specific pages in AEP Web SDK

While I haven't worked with WebSDK, you can create Activity Map exclusions but defining a specific exclusion using s.ActivityMap.regionExclusions

Since the Web SDK is really just how the data is being sent to Adobe, and it should still be using the ActivityMap JS code, this should work... I would try setting this up, then wrapping the entire page with the defined exclusion region.
