Wrong window. In HDRP, fog is decoupled from the rendering / lighting tab. Volumetric fog is a "component" you can add to a thing called "volume". Basically works like former Post-Processing stack V2.
Right click in your scene hierarchy: "Volume / Sky and Fog Volume"

If you're new to HDRP, it's worth wachting this official video tutorial: https://resources.unity.com/uniteno...ng-high-fidelity-graphics-for-games-with-hdrp

 

Hi i have a more a question. I cant add grass in terrain... I get this error " unity the current render pipeline is does not support detail shaders " https://pasteboard.co/JDWDQiK.png ( photo link )

 

Yes, unity HDRP does not support default terrain grass (Or yet it don't for me in unity 2019.4 and HDRP 7.3.1). You'll have to use an asset for that like vegetation studio, or to put grass gameobjects yourself.

 

Okay, Thank you I have ask a question more. How can i add grass with animation, or tree.Because Trees and Grass dont move leaves ( not swinging in the wind )

 

It can be done in your grass shader, I advise you to find an asset doing it for you, or to find a tutorial for a way to make grass with shadergraph.
