   You can get a Mutable ObjectFactory which you can then load an existing instance from a configuration node.

   ObjectMapper.Factory factory = (ObjectMapper.Factory) Objects.requireNonNull(node.options().serializers().get(type));
   ObjectMapper.Mutable<T> mutable = (ObjectMapper.Mutable<T>) factory.get(type);
   mutable.load(instance, node);

   is this a right approach?

   @SneakyThrows
   private void reload(final boolean ensureAsync) {
     if (ensureAsync) {
       PluginExceptions.ensureAsync();
     }
     synchronized (this.lock) {
       final var loader = Configurate.yaml(
         this.directory.resolve("messages.yaml")
       );
       final var node = loader.load();
       final var factory = (ObjectMapper.Factory) Objects.requireNonNull(node.options().serializers().get(AnnouncementMessages2.class));
       final var mutable = (ObjectMapper.Mutable<AnnouncementMessages2>) factory.get(AnnouncementMessages2.class);
       mutable.load(this, node);
       node.set(AnnouncementMessages2.class, this);
       loader.save(node);
     }
   }
