Yes, you can freeze gluten free Duvshaniot cookies if you want to. Place them in a freezer-safe bag or storage container, and they will last 1-2 months in the freezer. This is great for planning ahead. When you are ready to serve, just take what you want out of the freezer and allow them to thaw. They will defrost within a few hours, and then you can eat them. You could even toss them in the microwave for 10-15 seconds to warm them up if you want to.
