Lakehouse Object Sharing onelake security role

Yes. There is no way to hide all data users through Lakehouse . Read all SQL End Point or Lakehouse is the last option in Microsoft Fabric Lakehouse. it is open source linux systems. For that, You need to work in Direct Lake Mode ( Power BI Desktop ) where there is a option of "Make changes to this model" and you can select/ deselect whatever you want. or there is an option of row level security in Power BI Service. Microsoft Fabric is a Unified Data where there is only one security at all.
