How to hide restock notification

Site URL: https://woodliving.dk/webshop/bord-rustic-gb2

Hi 

On my webstore I have this product that is sold out. this item is a on-off-a-kind and I want to hide the waitlist section for this item.

I can hide restock notification for all products, but I really what to hide the restock notification for all item belonging to a specific category.  Like <article class = "category-borde">

<article class="sqs-pinterest-products-wrapper ProductItem hentry category-borde tag-palletr tag-spisebord tag-konferencebord tag-rustic author-michael-roepstorff post-type-store-item on-sale sold-out products-collection-v2" data-item-id="5dea232497b2c53a5ec3789e" id="yui_3_17_2_1_1661321222427_193">

The following code will hide all restock notifications. I just don't know how  to combine/target that article class = "category-borde" into this code.

/Start: Hide waitlist for BORDE
.product-restock-notification {
  display: none !important;
}
//End: Hide waitlist for BORDE

Please help. I know you guys are great.

Thanks you so much. 
I see that the .category-borde and  .ProductItem-details narrow is down so .product-restock-notification can be targeted. 
And your sniplet works like a charm.
