@bhuddah ,

- name: "Update only specified attributes"
  checkmk.general.host:
    server_url: "http://myserver/"
    site: "mysite"
    automation_user: "myuser"
    automation_secret: "mysecret"
    name: "my_host"
    update_attributes:
      labels: { "thisisatest": "this is a test" }
    state: "present"

works and is idempotent!

ansible [core 2.17.13]
Checkmk CEE Edition 2.4.0p12

might be an issue with literal block scalar, '|'

    update_attributes: |
      {
      "labels": { "thisisatest": "this is a test" }
      }

which does not work in my case at all
