I came across this guy who came up with a way to share some of his org-roam notes, and the strategy he uses could apply to your work situation. He keeps everything in one org-roam database, but for the notes he's sharing with the general public:

1. He stores them in a separate directory neuralnomicon/nodes.
2. He tags them as neuralnomicon.
