How to load dconf for root user?

Some research done:

• https://forum.antergos.com/topic/7896/gsettings-and-dconf-as-root-tutorial-sort-of
• https://askubuntu.com/questions/1134453/how-to-run-gsettings-for-another-user-ubuntu-18-04-2-lts
• https://docs.ansible.com/ansible/2.4/become.html

My (working) solution:

---
- name: Load dconf settings
  command: dconf load /
  args:
    stdin: "{{ dconf_contents }}"

- name: Load dconf settings for root
  command: dbus-launch dconf load /
  args:
    stdin: "{{ dconf_contents }}"
  become: true
  become_flags: -H

Settings are loaded from file.
