Is it possible to exclude a transaction from voting within a transaction?

Each transaction is within the range of transactions for voting. And TS works like everything has nothing.

I want to wrap several methods with a transaction.

using(var ts = new TransactionScope())
{
    DoSomething1();
    DoSomething2();

    ts.Complete();
}

Both methods open connections and try to commit. They try several times to reconnect with the transaction in case of lock timeouts. Therefore, I need to exclude unsuccessful transactions from the vote and leave successful.
