Undeline links only to links no other content or share icons in posts

Hallo , i have noticed a difficulty in GP with underline content only in blog posts or regular links all over the site, i have noticed that this is a must for accesibility for wordpress themes in repository from the Theme Team and i am curious why Generatepress does not have this option " To disable / enable " underlines for posts.

Anyway i try to figure it out myself and all topics i have found at least does not help ,

I have managed to make this style for links in posts only

.single .entry-content a {
    background-color: rgba(255, 255, 255, 0);
    color: #6BCBCA;
    background-image: linear-gradient( transparent 2px, #79CD6C 2px, #79CD6C 4px, transparent 4px ), linear-gradient( transparent 2px, #d8dce9 2px, #d8dce9 4px, transparent 4px );
    background-size: 0% 6px, 100% 6px;
    background-position: 0 bottom, 0 bottom;
    transition: background-size 0.1s ease-in-out;
    background-repeat: no-repeat;
    padding-bottom:2px;
}

.single .entry-content a:hover{
   color:#79CD6C;
   background-size: 100% 6px;
   background-color: #79CD6C00;
}

But here there is also Novashare Share icons underlined - > https://www.funkycss.com/the-latest-trends-in-design-and-color/

Also in the hidden link of my site , all links are underlined of woocommerce blocks, how can i fix this issue ?

Thanks you in advance!
