I had a very quick look at the code and I don't think it can be done
without a change to the engine. One way to do it would be to implement:
CefApp::OnBeforeCommandLineProcessing()

In revbrowser/src/cefbrowser.cpp

It could be a fixed command line argument that is added if no-one is
concerned about the security implications, otherwise some new command in
LiveCode that lets you add to this argument list before you create a new
browser object. The second option would obviously be much more flexible.
