Certain blocks are included by default (a full list is here). Some child themes may not utilize a section, so it would make sense to remove it entirely so users are not confused.

Remove an entire block from the tabbed list and their related settings.

function my_remove_block( $blocks ) {
	unset( $blocks['footer-widgets'] );
	return $blocks;
add_filter( 'gppro_admin_block_remove', 'my_remove_block' );
