Hello,

To remove the Add to Cart button from Products on Hover, please try using the below Custom CSS code and paste it to Dashboard >> Theme Settings >> Custom CSS >> Global CSS section:

.wd-hover-quick:hover .wd-add-btn {
  display: none !important;
}

For the Fade and Zoom-out disabling, please try out the following Custom CSS:

.product-grid-item .hover-img {
    transition: none !important;
}

For the time being, we have applied the CSS on your Site.

Best Regards
