Hi sZone,

Thanks for your interest.

Yes, you are right there are no such options right now. But you can use custom CSS anytime.

Here is the sample code for you:

.sppb-addon.sppb-addon-popover .sppb-card-body {
    background-color: rosybrown;
}
.sppb-addon.sppb-addon-popover .sppb-card-media-top>picture img {
    border-radius: 30%;
}

Here is all about custom code: https://www.joomshaper.com/documentation/helix-framework/custom-code-css-js-meta

Hope this helps:)

Best Regards
