To enable Screen Space Global Illumination (SSGI), you will first need to enable it in your HDRP Asset. For a guide on how to do this, see Unity's official tutorial.

Next, you will need to enable it through UniStorm. You can find this setting by going to the Celestial tab and opening the Sky & Lighting Settings. It can be found at the top. Ensure this is set to Enabled as by default it's disabled.
