Blazer date of build?

I know my 2019 Blazer's build year is 2019 (the 10th digit in the VIN is K), but I'd like to know the exact date of build (or at least the month). There's no build date in the documentation that came with the car, and there's no sticker with the build date in the driver's door jam, either. I wonder if there's any other way to find out the build date.
