aws_fms_policy-DeleteUnusedFMManagedResources

Hi Team,
I am struggling to find the relevant attribute for “DeleteUnusedFMManagedResources” in the terraform aws_fms_policy documentation for terraform;
can someone confirm that this is supported in terraform or not?
{
aws_fms_policy | Resources | hashicorp/aws | Terraform Registry
}

AWS:
Policy - AWS Firewall Manager (amazon.com)

thanks.

If anyone can confirm.
Thanks
