You actually can manually modify the nVidia (active amor) firewall. There should be a shortcut icon on your desktop called "NVIDIA Firewall". Double click that and go to Firewall --> Advanced Configuration --> Application. They should see Elemental listed here.
If it's not there, go to Active Armor --> Application and click the button called "Add Rule". You should now be in the menu called Active Armor Application - add rule. There should be three fields with the cursor flashing in the top one called "Please pick and application". To the right of that, you'll see a button called "Browse". The they should just browse to the elemental executable.
Once you've found it in the nvidia firewall "add rule", click it to paste the path into the rest of the fields in the Active Armor menu. Finally, change the two fields called Offload enable/disable for inbound connection and the Offload enable/disable for outbound connection to "Not Offloadable". Click "Apply" and you should see that the data has been added to the Active Armor Application Table. You can now close the firewall menu.
Been awhile since I have messed with it and options may have changed. Also, we may be talking about two different things. 
Edit: If for some odd reason it won't let you make changes follow the below instructions I dug up.
Changing any setting requires a custom profile, which you can set under the Basic Configuration page under Firewall. Pick Custom 1 (custom), rename it to something more fitting, and establish some baseline rules by regenerating one of the other security profiles. The Medium setting is probably most universally sound. Now you’ll have access to several wizards and all the options under Advanced Configuration.
