Does Loki storage_config support Azure storage account without hard-coded credentials?

Dear all,
I’m new to Loki and I’m trying to deploy Loki in an Azure VM connecting with an Azure storage account. From the Loki document it says the storage_config should be:

storage_config:
  azure:
    # For the account-key, see docs: https://docs.microsoft.com/en-us/azure/storage/common/storage-account-keys-manage?tabs=azure-portal
    account_key: <account-key>
    # Your azure account name
    account_name: <account-name>
    # See https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blobs-introduction#containers
    container_name: <container-name>

I would like to know if it’s possible to config storage_config without hard-coded credentials? As I can assign this Azure VM with managed identity, it can access(read/write) this storage account resource without any credential. Thanks in advance!
