Code
add_filter( 'wp_theme_json_data_theme', function ( $theme_json ) {
return $theme_json->update_with( array(
'version' => 3,
'settings' => array(
'blocks' => array(
'core/image' => array(
'lightbox' => array(
'enabled' => true,
'allowEditing' => true,

Images linked to a page or file keep their link instead of the lightbox. Editors can still turn it off per image.
