dsn less connection using text driver

I am trying to do ODBC import with DSN-Less connection(using text driver). Is there any way to tell SQLDriverConnect to set COLNAMEHEADER=yes/no? OR I need to use schema.ini to do it? Actually i don't want to create schema.ini manually, Can I use SQLConfigDataSource for dsn less connection? I haven't found any docs regarding this.

Thanks in advance, Manoj
