Disable function in Power Bi Auzure form end users

HI

We are currently testing Power BI in Azure. One issue we notice is the function down in the left hand corner "Get Data", the function where a end user can access a local file (i.e. excel) and upload that to azure and use in Power BI.

As this will open upp the possibillity for a security risk, i.e. if a end user have a excel file with data that is not sutible for a cloud service (according to our legal), we would like to dissable this function.

Is this possible?

Is it on the way to be a possibillity in upcomming release?
