AWSKMS Seal support AWS Identity and Access Management Roles Anywhere

Our Requirement is to use awskms seal type for auto-unseal HashiCorp Vault deployed on OCP containers.

One way is to provided IAM credentials in AWSKMS stanza but that is forbidden in my organization.

Does vault also support AWS Identity and Access Management Roles Anywhere mechanism to obtain credentials and then use it for auto-unsealing?
Vault use official AWS SDK so looks like its possible, but we dont know how to achieve the same.

Could you please help us in this regards.

Review the AWSKMS stanza and the described OCP deployment context first. Determine whether AWS Identity and Access Management Roles Anywhere is supported for auto-unsealing, and define the required chart or configuration changes if it is not. Done should include a documented, reproducible way to use the mechanism or a clear statement of its scope.
