Chains are not ideal, if you want to keep your gravel in place.
I plow 325' of gravel drive, (flat), with a loader mounted plow, turfs, no chains, no problem.
I added pneumatic, catering gauge wheels to my plow, so it stays and inch or two, above the gravel.
I keep the backhoe on, for ballast.
Packing down the first 3-4 inches of snow, is definitely the best way to keep the gravel in place.
In the spring, I have almost no gravel in the lawn.
