Jellybean 4.2.2 Phone radio settings (Verizon)

Are there any guides or info on where the phone radio settings are stored in Jellybean 4.2.2 for the Verizon network? I'm thinking somewhere in settings.db?

My main interest is to try to find a setting that will prevent my phone from connecting to any network extender. Any information specific to this setting would be much appreciated.
