Sorry to tell don’t think we can provide zone.
Instead can use the “alloc-ranges” property to specify the region of memory which is acceptable to allocate from.

		generic_reserved: generic_carveout {
25 			compatible = "nvidia,generic_carveout";
26 			size = <0 0>;
27 			alignment = <0 0x100000>;
28 			alloc-ranges = <0x1 0 0x1 0>;
29 			no-map;
30 			status = "disabled";
31 		};
