from a reference in https://wiki.dendron.so/notes/6DZiBObwhZNYRjnokQ422/

for access control, multi-vault lets users configure specific vaults to be private which turns off publication and sharing of any notes inside said vault

After reading this I assumed I could mark a confidential vault as private so that if I tried to reference it in another vault, it wouldn't work. I have a confidential remote vault that I want to prevent myself from accidentally referencing it in another shared/non-confidential vault. I can't find a property or way to do this from the docs, am I missing something or is my assumption wrong?
