Default [Q] Will flashing to an AOSP ROM enable me to toggle LTE?

I'd like to turn off LTE on my VS980 (to just use 3G), but apparently Verizon has removed the ability to do so and none of the apps out there can open the necessary settings window. My question is, if I put CM 10.2 on there, will I now have the ability to turn off 4G and save battery power?
