Hi Vikash,
yes, we have done it before by using MS OLE DB driver, available from MS website https://learn.microsoft.com/en-us/sql/connect/oledb/download-oledb-driver-for-sql-server?view=sql-server-ver16.
It needs to be installed directly on the Board server (also for Board cloud customers) and configured as an OLE DB connection from the Data Sources section in Board.
