What is the significance of selecting a customer-managed key for Azure VM disks?

Once selected, you cannot switch back to a platform-managed key.

Explain the difference between Service-managed keys and Customer-Managed Keys in Azure Key Vault.

Service-managed keys are convenient with low overhead, while Customer-Managed Keys offer full control over the keys.

What is the purpose of Service-managed keys in customer-controlled hardware (host your own key - HYOK) in Azure Key Vault?

To allow managing keys in a proprietary repository.
