Remove the link in the site title

Hi,

I’m trying to make the site-title of my page not a link (text only).
First I searched in the header.php but couldn’t find the right section. Then I discovered this part in the functions.php:

/**
 * Site branding
 */
if ( ! function_exists( 'oria_branding' ) ) :
function oria_branding() {
	if ( get_theme_mod('site_logo') && get_theme_mod('logo_style', 'hide-title') == 'hide-title' ) :
		echo '<a href="' . esc_url( home_url( '/' ) ) . '" title="' . esc_attr(get_bloginfo('name')) . '"><img class="site-logo" src="' . esc_url(get_theme_mod('site_logo')) . '" alt="' . esc_attr(get_bloginfo('name')) . '" /></a>';
	elseif ( get_theme_mod('logo_style', 'hide-title') == 'show-title' ) : //Show logo, site-title, site-description
		echo '<a href="' . esc_url( home_url( '/' ) ) . '" title="' . esc_attr(get_bloginfo('name')) . '"><img class="site-logo show-title" src="' . esc_url(get_theme_mod('site_logo')) . '" alt="' . esc_attr(get_bloginfo('name')) . '" /></a>';
		echo '<h1 class="site-title"><a href="' . esc_url(home_url( '/' )) . '" rel="home">' . esc_html(get_bloginfo('name')) . '</a></h1>';
		echo '<h2 class="site-description">' . esc_html(get_bloginfo( 'description' )) . '</h2>';
	else : //Show only site title and description
		echo '<h1 class="site-title"><a href="' . esc_url( home_url( '/' ) ) . '" rel="home">' . esc_html(get_bloginfo('name')) . '</a></h1>';
		echo '<h2 class="site-description">' . esc_html(get_bloginfo( 'description' )) . '</h2>';
	endif;
}
endif;

I think this is the right section, but I’m not quite sure how/where to edit it correctly to disable the link.

So any help would be much appreciated!

PS: Yes, I’m using a child theme.
