Hello,
I saw the screenshot you attached. Unfortunately, there is no option in Theme Settings to edit the my-account page. Because the MyAccount is WooCommerce functionality and our theme doesn’t influence it.
You can hide the particular item using Custom CSS. To hide the downloads option you need to add the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.
.woodmart-my-account-links .downloads-link {
display: none;
}
Best Regards.
