How to write this query without for loop

Question

I have three tables with m-to-m relationship. Customer - CustomerCars - Car

I receive a dictionary with a CustomerId as a key and an array of his CarId as value

public IDictionary<int,IEnumerable<CarsIdsDto>> Data { get; set; }

I want to delete some cars from many customers(CarsIdsDto are the Ids of cars that must remain), so my code for this looks like this

foreach (var entry in message.Data)
{
    var cars = await _context.CustomerCars
        .Where(x => x.CustomerId == entry.Key)
        .ToListAsync(cancellationToken);

    var newIds = entry.Value.Select(x => x.CarId).ToList();

    //Delete
    var carsToDelete = cars.Where(x => !newIds.Contains(x.CarId));


    await _context.CustomerCars.RemoveRangeAsync(carsToDelete,
        cancellationToken
    );
}

The code works fine, but it creates a query for every customer Can it be refactored to delete all customer cars in one query?
