C# Selenium WebDriver not respecting debugger port

I'm not entirely sure of what's going on. I'm setting my debugger port in my ChromeOptions, however, Selenium wants to connect to whatever port it feels like. What am I doing wrong?

                var driverInstructions = new DriverInstructions();            driverInstructions.Driver = Driver.Chrome;            driverInstructions.DriverLocation = @"M:\driver\127\chromedriver-win64 (5)\chromedriver-win64";            ChromeOptions options = new ChromeOptions();            options.DebuggerAddress = "localhost:9992";            sl.StartDriver(driverInstructions, false, options, false);
