PutBucketAcl and PutObjectAcl calls fail if the specified ACL is public.
PUT Object calls fail if the request includes a public ACL.
PUT Bucket calls fail if the request includes a public ACL.

Enabling this setting doesn't affect existing policies or ACLs.

This property is not supported for Amazon S3 on Outposts.

Type: Boolean
