Is there a way to disable SessionMerging for Webbrowser Control through a registry key (Internet Feature Control Key)?

Is there a way to set the SessionMerging key (sessionmerging=0) for Webbrowser Control through registry (Internet Feature Control Keys)?

As described in...

https://msdn.microsoft.com/en-us/library/hh826025
... it's possible to start Internet Explorer through the command line with the "-nosessionmerging" option
... or to set it within the registry HKEY_CURRENT_USER > SOFTWARE > Microsoft > Internet Explorer > Main >>>   "SessionMerging - (DWORD) 00000000"
- to force Internet Explorer making a new session (e.g. for not sharing session cookies) for each new browser tab or window.


I looked through the Internet Feature Control Keys documentation in https://msdn.microsoft.com/en-us/library/ee330720(v=vs.85).aspx but did not find what I am looking for.

The goal would be to set "SessionMerging=0" for a specific application, that embedds a webbrowser control. So that every web browser control within this application opens a new session, behaving like internet explorer started with the "nosessionmerging" option through the command line.


I found a blog entry from 2009 and a reply of EricLaw to the same question that sounds not very promising to me:

 @accesine: No, the web browser control does not expose control of sessions to the host.  You cannot (in a supported way) have multiple sessions running within one application."

But some years went by, maye there is a Internet Feature Control Key nowadays?
