Organic Search Listings - Can I change the links shown?

We operate 3 Shopify stores (Australia, UK and USA) all under the same brand with basically the same catalogue of products and website content. We service our Canadian customers from our UK site as the US site only trades in USD, but if you search for the brand name with a VPN set to Canada, the organic listings include a link to our US site. I'm assuming this is due to google trying to match the links to your location, but in this case we don't want the link to the US site. Is there a way to alter the results google returns?
