Hello,
Add to cart button appears on the hover of the product with the hover effect that you chose and you will have 2 add to cart button, is that ok for you? If you choose the Default type of hover effect then you will have the following view https://prnt.sc/td2OA1H4Nd-o
In case you want to have the double add to cart on hover and below then enable that option and hide q-ty using custom CSS
.content-product .quantity-wrapper .quantity {
display: none;
}
Regards
