I need to NOT render for example [Google](http://google.com) into this <a href="http://google.com">Google</a>
Instead I want to result to be [Google](http://google.com)

How do I go about setting up the pipeline this way?

You can try to create an extension that would remove the LinkInlineParser predefined in MarkdownPipelineBuilder

@xoofx Thank you for pointing me in the right direction. I was able to remove it with something like this:

 class Program
    {
        static void Main(string[] args)
        {
            var sampleMarkdown = "[Google](http://google.com)";

            var modelPipeline = new MarkdownPipelineBuilder();
            var removeLinks = new RemoveInlineParser();

            modelPipeline.Extensions.AddIfNotAlready(removeLinks);
            var pipeline = modelPipeline.Build();

            var renderedHtml = Markdown.ToHtml(sampleMarkdown, pipeline);

            Console.WriteLine(renderedHtml);
            Console.ReadLine();
        }
    }

    class RemoveInlineParser : IMarkdownExtension
    {
        public void Setup(MarkdownPipelineBuilder pipeline)
        {
            //Remove LinkInlineParser
            var parser = pipeline.InlineParsers.First(o => o is LinkInlineParser);
            pipeline.InlineParsers.Remove(parser);
        }

        public void Setup(MarkdownPipeline pipeline, IMarkdownRenderer renderer)
        {
            //Nothing to do here.
        }
    }

You can access the parsers on the builder, so you should be able to simplify that to

var builder = new MarkdownPipelineBuilder();
builder.InlineParsers.TryRemove<LinkInlineParser>();
MarkdownPipeline pipeline = builder.Build();

I was just about to post! I was playing around with it a bit more, and indeed the Extensions don't seem nescessary.

        static void Main(string[] args)
        {
            var sampleMarkdown = @"[Google](http://google.com)";

            var modelPipeline = new MarkdownPipelineBuilder();

            var parser = modelPipeline.InlineParsers.First(o => o is LinkInlineParser);
            modelPipeline.InlineParsers.Remove(parser);

            var pipeline = modelPipeline.Build();

            var renderedHtml = Markdown.ToHtml(sampleMarkdown, pipeline);

            Console.WriteLine(renderedHtml);
            Console.ReadLine();
        }
