is available & license keys can be accessed via Admin Console/Help/License Keys...here you can add/delete license keys, show summary of active features, active capacity-based features etc etc.
From the man page for bpminlicense:
"...
The bpminlicense utility manages a NetBackup license file. The preferred method to manage NetBackup licenses is to use the Help > License Keys panel in the NetBackup Administration console. For UNIX servers, you may use the get_license_key(1M) utility to manage the NetBackup licenses, which is preferred to this command.
..."
Not sure about your specific requirements tho'.
