Nethereum C# BlockProcessor how to set MinConfirmations

Question

I'm trying to process the most recent Blocks with a BlockProcessor in Nethereum. I think by default it is waiting for 12 block confirmations before processing them. How can I set the minConfirmations to 0?

        var processor = web3.Processing.Blocks.CreateBlockProcessor(steps =>
        {
            steps.TransactionStep.SetMatchCriteria(t =>
                addresses.Contains(t.Transaction.From));
            steps.TransactionReceiptStep.AddProcessorHandler(tx => HandleTx(tx));
            //steps.FilterLogStep.AddProcessorHandler(l => filterLogs.Add(l));
        });

        //if we need to stop the processor mid execution - call cancel on the token
        var cancellationToken = new CancellationToken();
        //crawl the blocks
        await processor.ExecuteAsync(
            toBlockNumber: new BigInteger(0),
            cancellationToken: cancellationToken,
            startAtBlockNumberIfNotProcessed: new BigInteger(14774327));
