Sure! You can use cookie crumbs using the same recipe for a graham cracker crust, especially chocolate cookie crumbs or shortbread crumbs. If you don't have any on hand, make some! Other items you can use in place of graham crackers are saltines, crushed pretzels, or potato chips. Or, go with the more traditional pastry pie crust. Just blind-bake and let it fully cool before filling it.
