Hello,
1. You can disable all these from Theme Settings >> Shop >> Disable all of them one by one: https://ibb.co/Nx4j8dW
And to disable the add to cart button from the product only from the homepage, please use the below custom CSS code:
.home .wd-add-btn.wd-action-btn.wd-style-icon.wd-add-cart-icon.wd-tooltip-inited {
display: none;
}
2. To increase the icons on mobile, please use the below custom CSS code and paste it to Theme Settings >> Custom CSS >> Mobile CSS section:
.whb-main-header .wd-tools-element .wd-tools-icon:before {
font-size: 30px;
}
Best Regards.
