In general those icons are not needed for users with disabilites, that's why we used those extra aria to "hide" them.
But yes, it's possibile to correct that. You have to override Feature addon (and Icon addon) and edit site.php file where you have to remove that extra phrase. Tip #7 from: https://www.joomshaper.com/documentation/sp-page-builder/sp-page-builder-3/how-to-tips
Social icons on the top1 have only aria-label that is 100% correct by all validators.
Icons used on top2 - indeed have aria-hidden - but anyway you have wrong contrast color there, Accessibility issue! To edit aria code you have to edit that file: templates/valur-purple/features/contact.php
ABout social icons at the bottom3 I don't know how you created it. If it was just custom HTML, just edit it.
