Ansible to SUBST a drive machine-wide

I've set up Ansible to connect to a Windows Server 2019 using WinRM certificate method. I need to map D drive to simply mirror C. With SUBST I can do SUBST D: C:\ but...

• When I run the command with Ansible using win_shell Remote Desktop does not show the drive.
• The opposite is also true: when I run the command with Remote Desktop, Ansible's shell does not see the new D drive.
• I tried using registry tricks to make the mapping persist, and after rebooting I can see the drive in File Explorer with Remote Desktop but neither PowerShell nor Ansible's win_shell see it.

How can I map C to D machine-wide using an Ansible playbook?

The registry value for the drive was missing \??\ prefix. Everything works correctly with the right registry value. For the record, this is the ansible task I ended up with:

    - name: Map D drive to C.
      ansible.windows.win_regedit:
        path: HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\DOS Devices
        name: "D:"
        state: present
        type: string
        data: '\??\C:'
