Licensing SQL upgrade to get Report Server

Hello,

Have a customer we would like to install PBIRS on their SQL server, they have SQL Server 2016 Standard. Has to be done on premise.

Couple questions:

Is it possible to upgrade and installed SQL Server 2016 from Standard to Enterprise w/ Quality Assurance so that Power Bi can now be installed?
Can SSRS and PBIRS run on the same host without issue?

Any help with this would be appreciated.
