Unfortunately that will exclude any Shopify powered store that has a custom domain.
Didn’t Google use to have an “inhtml:” operator or something that let you search for matches in the html of pages? Shopify powered websites have commonalities in their html that can give away very quickly the fact to a crawler that it is powered by Shopify, just by looking at the html of the main landing page of the shop.
Also, the DNS entry for a Shopify hosted site, even if using a custom domain, will be either a CNAME pointing to shops.myshopify.com, or an A record pointing to an IP address owned by Shopify, like 23.227.38.65. https://who.is/whois-ip/ip-address/23.227.38.65
