helm registry login --password-stdin in Azure DevOps pipeline

Question

- task: AzureCLI@2

  inputs:

    azureSubscription: $(azureSubscriptionForACR)

    scriptType: 'ps'

    scriptLocation: 'inlineScript'

    inlineScript: |

      $password = az acr credential show -n $(azureAcrName) --query passwords[0].value

      helm registry login $(azureContainerRegistry) --username $(azureAcrUserName) --password $password

I tried to log in to my private ACR using Azure DevOps pipeline using this method and it works but it shows a warning

"WARNING: Using --password via the CLI is insecure. Use --password-stdin."

please suggest a way to avoid this warning.

I am using the new helm 3.8.0.
