The generate_header_element_display allows us to bypass the Display Rules, so we can enable or disable an Element under our own conditions.

For example, if we want to assign a specific header to Author Tom only:

add_filter( 'generate_header_element_display', function( $display, $element_id ) {
    if ( 10 === $element_id && is_author( 'Tom' ) ) {
        $display = true;

    return $display;
}, 10, 2 );

Another request that we get from time to time is to only show page hero on first archive or posts page and turn off for 2nd and subsequent pages of posts. This can be done with the snippet below:

add_filter( 'generate_header_element_display', function( $display ) {
    if ( is_paged() ) {
       $display = false;

    return $display;
} );
