Json – How to prevent Jackson from serializing @class attribute in lists with known types?

I’m using Jackson in my Java application to serialize objects that contain lists of a known type. However, Jackson is adding an @class attribute to each item in the list, which I want to omit. Here’s an example of the JSON output:

[
  {
    "@class": "com.example.model.Resource",
    "id": "Resource_1",
    "version": 0,
    "reference": false,
    "items": [
      {
        "@class": "com.example.model.Item", // I want to remove this
        "id": "Item01",
        "version": 0,
        "status": "ACTIVE",
        "index": 1,
        "url": "https://example.com/item/1"
      },
      {
        "@class": "com.example.model.Item", // I want to remove this
        "id": "Item02",
        "version": 0,
        "status": "ACTIVE",
        "index": 2,
        "url": "https://example.com/item/2"
      }
    ]
  }
]

Since the type of the items in the list is already known (Item), the @class attribute is redundant. How can I configure Jackson’s ObjectMapper to prevent it from adding the @class attribute to list elements when their type is known?

Additional Info:

I’m using polymorphic type handling elsewhere in my application, so I can’t disable it globally.
I only want to suppress the @class attribute for specific lists where the type is explicit.

Disabling Default Typing: I considered disabling default typing globally using mapper.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);, but I can’t do this because I’m using polymorphic type handling elsewhere in the application.
