Metadata security without limiting visualizations

Currently Power BI has two security functions of OLS and RLS. With RLS you can secure your data based on the user that logs in, however, when you use embedding your PBI report in Power Apps Portal, it is possible to view the metadata through the queries which can cause a security concern and potential threat. On the other hand, if you use OLS, you can secure the metadata but at the cost of breaking your visualizations. It would be good if a solution could address metadata security without limiting or breaking the visualizations that use that data.
