No, Wix's websites are self-hosted, so you can't choose another hosting provider if you're already paying for a Wix subscription. On top of that, Wix makes it pretty difficult to transfer your site to another provider (such as Hostinger). You'll need to either use an RSS feed to import all of your posts to your new website or an FTP app to download all the files then upload them to the new host. Note that transferring your domain name is an entirely separate process from transferring your website.
