Hide One Variant Option if Product Has Siblings Pipeline

How can I hide the color variant on products that have a sibling attached to them, but keep the color variant when there isn’t a sibling on the product? I’m using the pipeline theme. I’ve attached a product image with siblings and one without.

Thank you!!

Hi @Mg71 ,
This is Theodore from PageFly - Shopify Page Builder App.

You can hide the color variant on products with siblings in the Pipeline theme using metafields and conditional logic.

Can you explain how to do that?
