I am sure they have the hardware but a tech willing to actually think and try scanning it OBD1 are completely different things.

When I brought my L99 car to the dealer for a AIR pump reflash the dumbass at the dealer that sold the car new argued with me that there never was a 4.3l V8 and swore the car had an LT1.

Dealership employees are more often than not parts swappers. There are exceptions but they are just that exceptions.
