Configure Magento 2 store URL's

Hi all, We are developing a Magento 2 shop with Apache stack. The main idea is create multiple websites (not store views) for each country. This is just to have the ability to specify different prices per country. I tried to set the following configuration: Stores -> Configuration -> Default -> Web -> Add Store Code to Urls It has a problem for us: it add the code to the Main Shop too. For SEO purposes, we want to have the Main Shop in the root. The final result must look like this: - UK (Main site): [login to view URL] - Spain: [login to view URL] - USA: [login to view URL] - Austria: [login to view URL] - Swisse: [login to view URL] - Belgium: [login to view URL] - Italy: [login to view URL] - Germany: [login to view URL] - Portugal: [login to view URL] - Netherlands: [login to view URL] - Australia: [login to view URL] - Canada: [login to view URL] The problem we are issuing is WE WANT THE MAIN WEBSITE (UK) IN THE ROOT /. We don't want to have the /uk URL (for SEO reasons). The deliverable will be: - Shops fully working - Detailed process how to add new countries The website is already mounted. Is just activate the multisite urls.
