What I meant was to remove managers from the document access template from the Identity Card document class. Since I thought the managers got their access that way.
Changing that line to No Access means that, by default, no access will be given to anyone, from a project, if a document is connected to a project. The document owner need to change it to View, Edit or Admin on each document that has project document access control.
But, setting that line to No Access for all document classes like that might not be what you want. Then project document access is more or less meaningless to have in the first place, unless every document admin sets the access to something else on each document.
I think I don’t understand what you want here, and the current setup you have, so I am not sure I can advice more. The answer should be in the documentation:

Good luck!
