Hi Victor,
I am assuming this link is "Switch to Calendar view". You can edit this file: /components/com_easyblog/themes/default/blog.archive.list.php and find and remove this code:
<a href="<?php echo EasyBlogRouter::_( 'index.php?option=com_easyblog&view=archive&layout=calendar' );?>" class="float-r"><?php echo JText::_( 'COM_EASYBLOG_SWITCH_TO_CALENDAR_VIEW' ); ?></a>
By the way, this is a core file of EasyBlog, and this will get override when you update EasyBlog. You can do template override for this file so that this file will not get override when updating EasyBlog. You can use this documentation as a guide:

Hope this helps.
