I cant find where imperial camels are enabled for Indians in genie editor

I can find where their tech tree is disabled, but how do i locate where they have the imperial camels enabled? I’d want to find the same for Vietnamese and Imperial skirmishers.

My goal is to give another civ those imperial units.

imperial skirmisher is different, similar to condottiero how it is enabled for allies.

imperial camel on the other hand is just tech 521
