Is *public_group_membership* exposed anywhere in the admin settings?

I’d like to be able to modify the number of groups a person can join in a minute from 3 per minute to 5 or 6 per minute. If I change the local rb file then surely that change will be lost every time I take the latest version of Discourse?
