In Ansible, how to set Execution-Policy to RemoteSigned?

Question

I have an Ansible role that executes Powershell scripts. I do this

- name: Set the execution policy to Unrestricted first
  win_shell: Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope LocalMachine -Force
  tags: always

- name: Start the services
  win_shell: C:\Users\Administrator\Desktop\Start_Services.ps1
  args:
    chdir: C:\Users\Administrator\Desktop\
  when: exa_services_state == "started"
  tags: always

- name: Stop the services
  win_shell: C:\Users\Administrator\Desktop\Stop_Services.ps1
  args:
    chdir: C:\Users\Administrator\Desktop\
  when: exa_services_state == "stopped"
  tags: always

- name: Set the execution policy to RemoteSigned
  win_shell: Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine -Force
  tags: always

However when the last task executes, I get the following

fatal: [10.227.26.97]: FAILED! => {"changed": true, "cmd": "Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine -Force", "delta": "0:00:00.640619", "end": "2022-03-04 05:33:29.496843", "msg": "non-zero return code", "rc": 1, "start": "2022-03-04 05:33:28.856224", "stderr": "Set-ExecutionPolicy : Windows PowerShell updated your execution policy successfully, but the setting is overridden by \r\na policy defined at a more specific scope.

If I go on the node and execute Get-ExecutionPolicy I see

PS: C:\Users\myuser>Get-ExecutionPolicy -List
        Scope ExecutionPolicy
        ----- ---------------
MachinePolicy       Undefined
   UserPolicy       Undefined
      Process       Undefined
  CurrentUser       Undefined
 LocalMachine    RemoteSigned

How can I avoid the error? Thanks!
