You may have to tweak the source code and add your attribute in the connect sub 
package DBD::mSQL::dr; # ====== DRIVER ======
use strict;

sub connect {
    my($drh, $dsn, $username, $password, $attrhash) = @_;
    my($port);
    my($cWarn);

    # Avoid warnings for undefined values
    $username ||= '';
    $password ||= '';

    # create a 'blank' dbh
    my($this, $privateAttrHash);
    $privateAttrHash = {
    'Name' => $dsn,
    'user' => $username,
    'password' => $password,
         # here ?
    };
