How can I change the do_action function in footer (copyright area)

Theme: Education LMS

How can I remove the theme information from my footer copyright area, or how can I edit the do_action function? So that only display what I want to display in footer.

                <div class="col-sm-6">                     <div class="site-info">                         <?php  do_action( 'education_lms_footer_copyright' ); ?>                     </div><!-- .site-info -->                 </div>                 <div class="col-sm-6">                     <?php                     wp_nav_menu( array(                         'theme_location' => 'menu-2',                         'menu_id'        => 'footer-menu',                         'menu_class'     => 'pull-right list-unstyled list-inline mb-0'                     ) );                     ?>                  </div>             </div>         </div>'
