if I have to return Azure storage account connection string (whose access key is disabled for security reasons) to DashboardConnectionString property of JobHostConfiguration class which I use in my web job and also not use Key vault. how to proceed ?

static void Main(string[] args)
{
    string topicName = "testtopic";
    string subscriptionName = "testname";

    string serviceBusConnectionString = ConfigurationManager.ConnectionStrings["ServiceBusConnectionString"].ConnectionString;

    subscriptionClient = new SubscriptionClient(serviceBusConnectionString, topicName, subscriptionName);
    subscriptionClientDeadLetter = new SubscriptionClient(serviceBusConnectionString, topicName, subscriptionName + "/$DeadLetterQueue");

    var config = new JobHostConfiguration { DashboardConnectionString = null };
    var host = new JobHost(config);
    host.RunAndBlock();
}
