So you have the latest FW update file availalbe, unfortunately this file will not allow you to make the chagnes you are trying to mak.The only way to make chagnes to the default settings, is to have the complete FW binary. The parameters section is not included in the FW update file. If you have the full Binary file then you can output the parameters file and make the changes - otherwsie you need to use a setup and configuration server to make a profile change. this is done to prevent rogue admins or hackers from modifying the settings without proper authentication.
if you have the full binary file then AMTNVM can make the changes.
