You can use Shopify’s hide a section option to hide the Subscription Widget from the storefront:

1. Log in to your Shopify admin and select Online Store.
2. Click Customize next to the theme you want to create product page templates for.
3. Click the page drop-down menu item at the top of the editor and select Products.
4. This opens the default product page. You must complete the steps again if you use custom page templates for your subscription products.
5. Click on the eye icon next to the Subscription Widget 2.0 section under Templates.
6. Click Save.

New customers cannot purchase products on a subscription basis when you hide the widget from your storefront. See Discontinuing subscription products to prevent existing customers from receiving your products.
