Have you tried looking for it? I hear the mod maker's workshop is a good place to start.

ive seen versions without the traditions but some of the trees are changed. i want traditions completely vanilla. example private colony doesnt work, the discorvy start bonus is different

There is an official version with No Traditions by petruxa, however he has not updated it to match the new features in the core mod since the mod name changed to add "Cultural Overhaul" to the title. It is very out of date. http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1133959816

Another user named Dinty Gadget is currently maintaining a more up to date version of the traditionless version. It isn't clear to me if pextruxa authorized that or not - as far as I am aware any arrangement was not publicly dicussed. It may be one or two updates behind the core mod, but this is the one you would probably want to get right now. I've used this version with a different traditions overhaul mod, no crashes or obvious conflicts, so I am pretty sure that confirms it works without touching traditions.
