Tricky question. First I thought it’s not possible but…
1. Enable lightbox for galleries.
2. Find the page/post ID where you’d like to disable the gallery
3. use rl_lightbox_args() filter like that:
function df_disable_galleries_on_specific_pages($args) {
// 12 is the page ID you'd like lighbox galleries to be disabled
if (is_page(12)) {
$args['activeGalleries'] = false;
}
return $args;
}
add_filter('rl_lightbox_args', 'df_disable_galleries_on_specific_pages');
