Enforce use of locked variables in Dashboard

We actively use embedded dashboards in our application. In particular, there are some variables which are always locked, as the questions for the dashboard contain the data of various users and we use the locked variables to ensure that the questions don't leak data they're not supposed to.
However, this is a manual process which is prone to human error. Given the potential risk of leaking data, is a feature that would allow a dashboard to be configured such that locked variables must be used by the questions? Perhaps this could even be configurable at the account level. If there's no such feature, is there some workaround I'm not aware of to automatically enforce use of locked variables or specific variables?


You will need to look into Data sandboxes but note that it's a paid feature
