You can identify the class or div attached to the author element (by broser inspecting F12) ,
for exemple :
<span>
<div class=”author”> your author name </div>
</span>
then all you need to do is add some JS or jQuery code (using a snippet or prebuild in theme)
——————-
JQuery :
jQuery(document).ready(function( $ ){
jQuery(“span”).remove(“.author”);
});
——————
JS :
var myobj = document.getElementByClassName(“author”);
myobj.remove();
