Basically, yes, but only with a SRAM 10sp rear derailleur. Leonard seems to only mention the XX, but Sram makes other 10sp mountain derailleurs with "exact actuation" technology, which ensures the same cable pull ratios as Sram road shifters. The 10sp X7 is the cheapest of these.

Sram doesn't make a brifter that will shift a triple. If you really need to run this bike as a triple you could do some crazy setup with a barend shifter in addition to your brifters.

Another crazy option would be to run a mountain double crankset. A 39/26 with an 11-36 cassette would get you 19.6 to 95.7 GI range. Running a 2x10 mountain crankset with a road fd might not work with a road derailleur because the chainrings are so much smaller. I poked around and I am not sure if you can run a Sram road shifter with a Sram 2x10 mountain front derailleur and Sram 2x10 mountain crank.

Also, why would you get a CX bike with a standard road crankset? 50x11 is still pretty fast if you can spin it. I wasn't aware that anyone sold a new cx bike like this anymore.
