Hello Steve,
Currently there's no settings available for this but you can always modify the theme file located in /components/com_easysocial/themes/wireframe/groups/item.header.php and remove the codes below at line 169,
<span>
<i class="ies-eye"></i>
<?php echo JText::sprintf( FD::string()->computeNoun( 'COM_EASYSOCIAL_GROUPS_VIEWS' , $group->hits ) , $group->hits ); ?>
</span>
I will also log this into our issue tracker to make this option configurable in the future
