On reprogramming, it's possible, but you have to unlock it. One guy was offering a service to unlock GM modules for around $300. A brand new module would be the same, it's shipped unprogrammed, without a specific VIN. The other thing you need is a running car to program it. An unlocked or new module needs to be installed into the car and then it's programmed for that car. So this would only work if you have a '19+ car that's exactly the same as your car you can use to program the new or unlocked module.
A few of us have done this successfully so it's possible... as cheap as the modules are in junkyards or ebay, maybe try again with a different one?

Good point about needing a '19+ car to train a brand new EBCM, unfortunately I don't have access to this option so it looks like I'll need to try another used EBCM. For the used EBCM, is there important matching criteria beyond the three items listed below? 1SS vs 2SS? Dual mode exhaust?
-'19+
-Transmission (MT vs. AT)
-SS 1LE configuration
