You can create a block list based on MAC address:

Hey Joshan,

Global Protect assigns a unique Host ID to identify each host. This ID value varies depending on the device type.

Windows—Machine GUID stored in the Windows registry (HKEY_Local_Machine\Software\Microsoft\Cryptography\MachineGuid)
macOS—MAC address of the first built-in physical network interface
Android—Android ID
iOS—UDID
Chrome—GlobalProtect assigned a unique alphanumeric string with a length of 32 characters

The document on my first comment will show you how to find this Host ID, however, it's still a Block List.

If you want to allow just a few workstations, have you considered using certificates? You can create a root CA on the Paloalto and use it to create device certificates. This will be alongside your existing authentication method, in this case, LDAP.

You can also distribute the certificates via a Group Policy.
