Hiding variants from storefront
If you have stock-managed variants that you do not want to show in the online store, we recommend that you hide them instead of deleting them from the product. This is because when deleting, you will lose stock history, and any links to stocktaking and purchase orders will be lost.
To hide a variant, click on the "Variants" tab inside the product, and scroll down to where you can choose to hide variants:
Once you have saved the change, the variant will be hidden from the online store and no longer possible for end customers to purchase.
