Translating gitlab-rails/config/gitlab.yml options into gitlab.rb

How can I set default values values from the generated gitlab.yml into the global /etc/gitlab/gitlab.rb config?

Specifically, I want to set global values for:
## Default project features settings
default_projects_features:
issues:
merge_requests:
wiki:
snippets:
visibility_level: # can be “private” | “internal” | “public”

But I can’t figure out how to translate that into /etc/gitlab/gitlab.rb options

gitlab_rails[‘default_projects_features_wiki’] = false

for example, doesn’t seem to work. Should this be possible?

You can follow the template https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/files/gitlab-config-template/gitlab.rb.template

It seems this was the right setting and yet it didn’t work?

My mistake, it did work…

Thanks though, that link is very useful.
