Currently, the link to the product page works only on the title and price. To make the whole section clickable in Shop Layout 05, add the following CSS in the Divi Theme Options:

.dfw-shop-05 .woocommerce ul.products li.product a:hover:before {
    background-color: rgb(0 0 0 / 80%);
    content: '';
    position: absolute;
    height: 100%;
    left: 0;
    top: 0;
    width: 100%;
    z-index: 1;
    transition: all 0.5s
}

.dfw-shop-05 .woocommerce ul.products li.product:hover:before {
    content: none;

}

.dfw-shop-05 .woocommerce ul.products li.product a {
    display: block;
}
