Question

Can I install a second instance of SQL Server on the same VM? Can I change installed features of the default instance?

Answer 1

Yes. The SQL Server installation media is located in a folder on the C drive. Run Setup.exe from that location to add new SQL Server instances or to change other installed features of SQL Server on the machine. Note that some features, such as Automated Backup, Automated Patching, and Azure Key Vault Integration, only operate against the default instance, or a named instance that was configured properly.
