Hi there,
There is no setting to do that currently.
You can copy the 
author.php file from 
JoomlaFolder/components/com_easyblog/themes/wireframe/blogs/entry/author.php and paste it at template override location which is at 
JoomlaFolder/templates/yourCurrentTemplate/html/com_easyblog/blogs/entry/author.php.
Take note that you need to create the folders manually if you don't see it.
After that, you can look for and remove the following PHP code in the 
author.php which is from the template override location:
<time class="pull-right"><?php echo $recentPost->getDisplayDate($this->entryParams->get('post_date_source', 'created'))->format(JText::_('DATE_FORMAT_LC1')); ?></time>
