Hello Iqbal,
Welcome to the Microsoft Q&A Community. Unfortunately, once enabled on an Azure Key Vault or Managed HSM, Purge Protection cannot be disabled or overridden, even by administrators. This feature is permanent and enforces a mandatory retention period (typically 90 days) during which deleted items cannot be purged. To address related issues, users can either wait for the retention period to expire, use a different name, or plan ahead for future deployments.
