Hi dermaticolombia,

1. May I misunderstood what your question. If you want to disable Sticky add to cart, then go to Theme Settings > Single product > Add to cart > and disable Sticky add to cart option https://prnt.sc/XJR4tWN5TA60

2. If you want to keep using Sticky add to cart and there is X button to close it while scrolling, then you can create a ticket here: https://woodmart.canny.io/feature-requests so our developers will consider such a feature.

Regards,
