Following your comment, here's how you can do:
Education Hub use hook to display header, so you it is possible to override education_hub_action_header hook inside a plugin like that
add a new php file in wp-content/plugins/ with following content:
<?php
/*
Plugin Name: h1 in homepage logo for education hub
Version: 1.0.0
*/
add_action('init', function(){
remove_action( 'education_hub_action_header', 'education_hub_site_branding', 10 );
});
add_action('education_hub_action_header', 'education_hub_site_branding_override');
function education_hub_site_branding_override(){
?>
<div class="site-branding">
<?php if ( is_front_page() || is_home() ) : ?>
<h1>
<?php endif; ?>
<?php education_hub_the_custom_logo(); ?>
<?php if ( is_front_page() || is_home() ) : ?>
</h1>
<?php endif; ?>
<?php $show_title = education_hub_get_option( 'show_title' ); ?>
<?php $show_tagline = education_hub_get_option( 'show_tagline' ); ?>
<?php if ( true === $show_title || true === $show_tagline ) : ?>
<div id="site-identity">
<?php if ( true === $show_title ) : ?>
<?php if ( is_front_page() && is_home() ) : ?>
<h1 class="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></h1>
<?php else : ?>
<p class="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></p>
<?php endif; ?>
<?php endif ?>
<?php if ( true === $show_tagline ) : ?>
<p class="site-description"><?php bloginfo( 'description' ); ?></p>
<?php endif ?>
</div><!-- #site-identity -->
<?php endif; ?>
</div><!-- .site-branding -->
<?php $show_search_form = education_hub_get_option( 'show_search_form' ); ?>
<?php if ( true === $show_search_form ) : ?>
<div class="search-section">
<?php get_search_form(); ?>
</div>
<?php endif; ?>
<?php
