[nobodyfrm]

These are site settings “hide_user_profiles_from_public”

@sam

for all the settings flagged with shadowed_by_global can be passed in via env:

Any settings that are not can be amended either via server api or you could include a script to change them. If you must amend the defaults you would need to create a custom plugin.
