Even Net::SCP::Expect has this option. This is how you pass this:

    my $scp_exp = Net::SCP::Expect->new(
                                         host     => $host,
                                         user     => $user,
                                         password => $pass,
                                         timeout  => undef,
                                         auto_yes => 1,
                                         recursive => 1,
                                         option => 'StrictHostKeyCheck
+ing=no'
    );
