How to stop real-time changes polling in issues and merge-requests pages?

We couldn’t find the “Application settings -> Real-time features” setting mentioned in https://docs.gitlab.com/ce/administration/polling.html

We’d like to stop, or decrease the polling interval, it’s way too frequent, thanks!

The setting is available under the Admin Area -> Settings -> Preferences section.

Visibility and access to the Admin Area requires use of the administrator account.

Hi, thanks very much for your answer

Is this a self-hosted setting only?
Our gitlab owner user can’t see that setting, we’re using gitlab.com CE edition

Is this a self-hosted setting only?

Yes, I should have clarified that all Admin Area application settings are only available over self-managed instances. There isn’t a way to configure the rate of UI state polling over the SaaS offering.
