Hi @Anonymous ,
As far as I known, there are two possible modes to connect to SQL Server Database.
Windows Authentication mode and mixed mode. Windows Authentication mode enables Windows Authentication and disables SQL Server Authentication. Mixed mode enables both Windows Authentication and SQL Server Authentication. Windows Authentication is always available and cannot be disabled.
I'm not familiar with key pair authentication, I could only do some online research for you about the key pair authentication in ODBC.
You may check below link to see if it is helpful.
