The only way of tuning early\_hint\_header\_mode is via global settings.

This is generally done by setting environment for the container:

`DISCOURSE_EARLY_HINT_MODE` can be `preconnect` or `preload` or `prefetch` or blank.

Self hosters would do so in that `app.yml` file.

This setting is only able to come with one value. Self hosters can validate what it is with:

```plaintext
./launcher enter app
rails c
> GlobalSetting.early_hint_header_mode

```

Early hints are a rather complex setup cause the proxy needs to support them and they are not supported by many proxies.
