Hi
Welcome to Microsoft community.
The issues on "Secure System" process / Virtual Secure Mode - I'd like my memory back now is out of reach of the response support community. It is more suitable for publishing on Microsoft Learn (English only). Here is a link to the forum, you can click on "Ask a question", there are experts who can provide more professional solutions in that place.
Best regards
