How to get rid of the pre-seted contextualization variables in vRouter creation process?

Please, describe the problem here and provide additional information below (if applicable) …

I’m trying to create a vRouter using pfSense as base, so far is partially contextualizated (I mean, from the Sunstone you can tweak several items (NICs, IPs, and so on) and the pfSense will recognize them and apply the changes).

I would be glad if I could get rid of the marked items in the following picture:

I have being trying to change some of the variables in the vRouter template, but this stuff are marked in iron in the Sunstone code or something. So: how can I get rid of those unnecesary (for my appliance) perks?
