I’d just follow mfg’s spec’s. Cement siding isn’t supposed to be in ground contact because it’ll wick moisture, not because it’s damaged by the water. Ground contact also encourages mold growth, but I’ve yet to see the siding actually compromised from moisture or mold.

What Chad said…plus contact with the soil would offer sheltered access to wood destroying insects. For that reason alone I see no reason to vary from whatever clearances are required in your region for wood siding.

The IRC would require at least 6" clear to grade (or 6" of exposed foundation) per R404.16 for foundation walls. Also note that R323.1 would require 8" clear to untreated sills in decay areas. See this link too.
