Murphy's Law states that just when you think you have shared all you have to give in a document you find a juicy tidbit that should have been included.  Therefore, I have updated the Intel® AMT™ Add-On for SMS from V3.3 to V5.0 Upgrade OverviewPDF. 

I discovered a batch file that is included in the default installation directory, C:\SMSAMTInstallation\iAMT addon for SMS\IAMTSMSSettingsExport.bat.  Within it contains the command line to export the registry settings for your currently installed version of the Add-on.
