How to Create Realistic Fog?

The default fog is very uniform. If I could add some noise the results will be better, but there is no option.
Perhaps create a volumetric fog with NanoVDB will be the solution, but i don’t know how to do it. Any tutorial or sample it´s possible? …or including a preset of fog in Omniverse Flow will be very useful.

Thanks in advance.
