The first four block 1 varients deployed to Afghanistan were pretty widely publicized. After that you can find public references to test events throughout the 2010s, the manufacturing of a few block 2 varients, and stated interest from more than one agency. But no there aren't a lot of hard numbers to be found in a Google search. Presumably you could learn more by looking through the actual contracts, but that takes some time and effort.

For a completely new military program, that's close to your best case scenario. Most new programs get dropped after the first prototype.
