Hey Akmal,

Sorry to say this, unfortunately we don't have a setting to disable it. But you can try modify in this following file:

JoomlaFolder/components/com_easysocial/themes/wireframe/dashboard/guests/default.php

Remove code from this line 14 to 16:

<div>

	<?php echo $this->html('html.login', $return); ?>

</div>

Then override this file into your current site template directory location
JoomlaFolder/templates/YourCurrentTemplate/html/com_easysocial/dashboard/guests/default.php
