Hi there,
You can remove the default layout for the author archive page by adding this PHP snippet.
add_action( 'wp', function() {
if ( is_author() ) {
remove_action( 'generate_archive_title', 'generate_archive_title' );
remove_action( 'generate_after_archive_title', 'generate_do_archive_description' );
}
} );
This removes the page title(the author’s name) and the description (author’s description/bio).
But if you only need to hook things on either the description or the archive title, you can use the hook specified on my snippet which are generate_archive_title
and generate_after_archive_title
