Resources separete from Repo (bitbucket)

I have a project that's gonna be well over 2GB (which is a hard cap for bitbucket) so my team divided code and assets. Code is pushed to bitbucket (entire /Assets/ without /Resources/) and Resources folder holds our heavy graphical assets and we send it via .unitypackage to each other once in a while when new batch of resources arrives.

How do we configure that setting in UCB? We can't build from repo alone
