Backup Pulse Secure Devices

I am looking for some assistance from you nice people.

I am trying to use NCM to perform configuration backups for some Pulse Secure devices, but the only references I have been able to find are 4+ years old, and a variety of it's not possible yet.  Can anyone share me some information or links on how to backup these devices, or is it not possible?

I would appreciate any assistance you could provide.  Thanks.
