Sorry for not being able to help you with your requirements.
We cannot block visitors even before visiting your website. Simply because we don't have access to handle Shopify backend or hosting.
Therefore, visitors must visit the site so that we can detect the location and the IP by our script and take necessary action based on the results. Since the initial visit is inevitable, your Google Analytics will still catch that initial visit.
