How to set up a campaign with strictly 3025 tech in RogueTech?

I'm looking for guidance on how to configure a RogueTech campaign where all available technology is strictly limited to 3025 Inner Sphere standards. That means no ClanTech, no LosTech—only the standard tech level available to the Inner Sphere at the time.

I don’t mind if the mechs, vehicles, or weapons come from later eras, as long as they don’t exceed the 3025 tech level. Is there a way to configure the settings to enforce this, or do I need to manually tweak faction availability or other settings?

Any advice or a step-by-step guide would be greatly appreciated!

Thanks in advance!
