What is the best way to get out of the naming situation in ansible deploy?

Question

Continuous Integration

For deployment, there is ansible playbook.yml

- name: Start Docker container api
      docker_container:
        name: "api_{{ target_host }}"
        image: "{{ api_artifact }}"
        recreate: true
        volumes:
          - "{{ app_dir }}:/app/storage"
        exposed_ports:
          - 5000
        env:
          HTTP_PROXY: "{{ HTTP_PROXY }}"
          HTTPS_PROXY: "{{ HTTPS_PROXY }}"
          LDAP_HOST: "{{ LDAP_HOST }}"
        networks:
          - name: "{{ project_name }}_network"
            aliases:
              - backend

ENV style - write in capital letters,
ansible vars style - write in small letters

I understand that write
LDAP_HOST: "{{ ldap_host }}"
and is free, BUT I wrote it this way because you can just copy and add lines from ENV and avoid unnecessary
errors in accordance

Is it possible to somehow get out of this situation in order to make the variables in small letters and send them to ENV in large letters?
