Sets whether uniform bucket-level access is enabled for this bucket. When this is enabled,
access to the bucket will be configured through IAM, and legacy ACL policies will not work.
When this is first enabled, uniformBucketLevelAccess.lockedTime will be set by the
API automatically. This field can then be disabled until the time specified, after which it
will become immutable and calls to change it will fail. If this is enabled, calls to access
legacy ACL information will fail.
Sets the bucket's Public Access Prevention configuration. Currently supported options are
PublicAccessPrevention#INHERITED or PublicAccessPrevention#ENFORCED
