How to combine two loops into one in Ansible

I have this part of code that is responsible for adding rule to Imperva for specific server.

There is a lof of nested variables so rather than explaining all parts of it I will just focus on a problem.

The issue is there can't be two loops inside of this task.

I added loop: "{{ list_of_codes }}" and there is also old part of code using with_items -> with_items: "{{ ic_dc_stat_list.json | default({}) | json_query('DCs[?name==Fontend_USA].id') }}"

This is the task I am talking about:

    - name: "Add [USA] Rule"
      run_once: true
      delegate_to: 127.0.0.1
      uri:
        url: "{{ ic_api_url_sites_rules }}/add"
        method: POST
        validate_certs: false
        body: "{{ ic_auth }}&\
        site_id={{ _site_id }}&\
        dc_id={{ ic_dc_stat_id }}&\
        name=USA&\
        filter=CountryCode == {{ item }}&\
        {{ rules.action.frw_dc }}"
      loop: "{{ list_of_codes }}"
      vars:
        ic_dc_stat_id: "{{ item }}"
        _site_id: "{{ ic_site_stat.json.site_id | default(incapsula_brand_domain.site_id) | default(site_id)}}"
      with_items: "{{ ic_dc_stat_list.json | default({}) | json_query('DCs[?name==`Fontend_USA`].id') }}"
      when: ( not ic_rules.json.delivery_rules | json_query('Forward[?name==`USA`]') )
            and ( ic_abigail and not ic_cs )
      register: ic_rules_latam_stat
      changed_when: "'skipped' not in ic_rules_latam_stat"

Loop list_of_codes should adding country codes here filter=CountryCode == {{ item }}.

This is details of mentioned loop:

list_of_codes:
 - "MX" # Mexico
 - "GT" # Guatemala
 - "HN" # Honduras
 - "NI" # Nicaragua
 - "CU" # Cuba
 - "DO" # Dominican Republic
 - "CR" # Costa Rica
 - "SV" # El Salvador
 - "PA" # Panama

I am looking for the best way to implement list_of_codes, but how to do this when there is already one loop in task -> with_items: "{{ ic_dc_stat_list.json | default({}) | json_query('DCs[?name==Fontend_USA].id') }}" which is used here: ic_dc_stat_id: "{{ item }}"

I though about jinja2, but now sure how to implement it here.

Please, help me to understand how to fix it.

To focus on the problem, let's assume we have the lists below

list_of_codes:
  - MX
  - GT

list_of_ids:
  - 1A
  - 1B

If the cartesian product is needed the playbook below

shell> cat playbook.yml
- hosts: localhost
  vars:
    list_of_codes:
      - MX
      - GT
    list_of_ids:
      - 1A
      - 1B
  tasks:
    - debug:
        msg: "{{ item.0 }} - {{ item.1 }}"
      with_nested:
        - "{{ list_of_codes }}"
        - "{{ list_of_ids }}"

gives

shell> ansible-playbook playbook.yml | grep msg:
  msg: MX - 1A
  msg: MX - 1B
  msg: GT - 1A
  msg: GT - 1B
