C# 包含上的EF核心停止递归

我正在使用.NET Core 3和最新的实体框架Core。我目前有3个表，两个普通表和一个链接表。它们的结构如下。我正在尝试为其链接到的车辆单独获取附件，目前正在发生的是，它返回到自身并再次加载车辆对象（因为它引用了链接表）。有人知道如何阻止这种递归发生吗？我不希望

VehicleAccessory

中包含

vehicleAccessories

数组，这会导致递归

呼叫

var result = _context.Vehicles
            .Include(x => x.VehicleAccessories)
            .ThenInclude(x => x.Accessory)
            .Include(x => x.VehicleImages)
            .ThenInclude(x => x.Image)
            .ToList();
        return result;
