Thank you.  Correct.  You can use MPC-BE/HC or PDVD for 3D MVC.  Since your source is only .mkv, you won't be able to use menus so MPC-BE/HC is a good choice and yes, follow the guide exactly.

Yes, HDR is the real deal and passes through.  I don't know what you mean by forced HDR activation?  Nothing is being tricked.  If your source is HDR, your display goes into HDR mode and plays HDR perfectly just as it would with a physical disc.  This occurs automatically and dynamically switches as needed.  I would suggest ripping your entire disc 1:1 and using DVDFab Player to mimic it precisely as the physical disc in a dedicated player but you can partially rip it to mkv and use MPC-BE/HC if you desire.    If you mean HDR converts to SDR:  You only need to change some settings to convert an HDR into SDR mode if your display is not capable of HDR.  This too is automatic and dynamically switches.  Understand, there is no tricking or unreal rendering going on.  This method provides a better picture than a dedicated player with a physical disc ever will by fine tuning many aspects a dedicated player simply isn't capable of.
