Hi @bastiaan1232 !
I understand that you would like to disable the notification that is asking customers whether they have a coupon code to use. Is that correct?
If so, you can disable it by unchecking Enable Coupons in WooCommerce > Settings > General > Enable Coupons
Here is a screenshot for reference: https://d.pr/95055v
Please note that this will disable the usage of coupons on your site! In case this is not the end goal please do let us know and we will take another look 🙂
Thank you!
