You can’t write inventory directly to variants, because we don’t know which locations the inventory should be allocated to. Managing inventory isn’t really on the variant, the inventoryQuantity is a convenience field that’s a rolled-up version of the existing quantities at the stocked locations.

Instead, use the inventoryBulkAdjustQuantityAtLocation mutation to change the inventory quantity of a specific inventory item.
