Hello Anirudh,
I am really sorry for the delay of this reply as it is a weekend for us here. It's currently not configurable but you can always add some css codes in the file /components/com_easyblog/themes/dashboard/system/dashboard.write.options.php and locate the codes below,
<?php if ( $this->acl->rules->contribute_frontpage ) { ?>
<li>
<label><?php echo JText::_('COM_EASYBLOG_DASHBOARD_WRITE_PUBLISHING_DISPLAY_ON_FRONTPAGE'); ?> :</label>
<div style="margin-top:4px">
<?php echo $this->renderCheckbox( 'frontpage' , $frontpage );?>
</div>
</li>
<?php } ?>
Replace it with,
<?php if ( $this->acl->rules->contribute_frontpage ) { ?>
<li style="display: none;">
<label><?php echo JText::_('COM_EASYBLOG_DASHBOARD_WRITE_PUBLISHING_DISPLAY_ON_FRONTPAGE'); ?> :</label>
<div style="margin-top:4px">
<?php echo $this->renderCheckbox( 'frontpage' , $frontpage );?>
</div>
</li>
<?php } ?>
