Missing X.509 section

According to the DIGI documentation there should be an section under the Administration tab that has X.509 that is used to end-end encryption. However this appears to be missing

The device in question is a USBAnywhere 8 Plus, Hardware Verision 3, and running firmware

Is this feature not available for this device? or is there some other way to access the setup for end to end encryption.

If this has not been answered yet, X.509 Certs is not yet an option for the AnywhereUSB Plus line currently. This will be added in the future but there is no current timeline.
