Hi JV,
There is no setting to disable this. However, you can perform a template override in the backend
Themes>Wireframe>Edit Template Files>/toolbar/default.php
Then remove this block of code and save.
<li class="<?php echo $view == 'users' ? 'is-active' : '';?>">
<a href="<?php echo ESR::users();?>" class="es-navbar__footer-link">
<i class="fa fa-users"></i>
<span>
<?php echo JText::_('COM_EASYSOCIAL_TOOLBAR_PEOPLE');?>
</span>
</a>
</li>

Let us know how it goes, thanks.
