Hi John,
I do not think so. This is in the FAQ section of WLC AVC feature.

Q. How can users load a protocol pack?
A. Using FTP or TFTP, users can download newer versions of protocol packs.
The command syntax is:
● Transfer download datatype avc-protocol-pack
● Transfer download start
● Default protocol-pack
Here is also some useful AVC guide with Prime Infrastructure.
