Leading zeroes to decimal value less than one

As its not a way to have custom code in vendor so can you help if there is any other way to set FormatDecimals = 1 ?

The parameter FormatDecimals is not supported in the current SQLSRV driver.
I recommend you send a bug report or a pull request to support it.

All you can do now is to create extended driver:
