I believe what you want is in this thread. Read through it and you’ll notice there is a file for comparison. IIRC everything I needed to get going was in the zip file. Using the compare feature in HPT highlighted the differences.

Your 2019 may be different but the principle should be the same in that you’ll manually make the changes. Not sure if you wanted a file to just put in the ECM. Unless you’re remote tuning, I’d suggest you manually make the changes and not install any tune file.

Quote from the thread:

23. The attached zip file contains a baseline HPT file for reference on enabling the Flex Fuel sensor only. All performance related tables are stock in the baseline file. The changelog.txt file will indicate what is required and what is optional (but highly recommended). I have not looked at a 2017 file so I do not know if everything for the 2016 will translate over. The stock Flex Fuel tables are very good from a performance perspective so you will realize a high increase in torque across the board without actually doing a dyno tune. If you make it this far take the time after installation to monitor knock retard and adjust accordingly. Depending on ambient conditions you might need to lower timing in the higher g/cyl areas of the high octane spark tables. GM did not optimize the timing when you start getting past 0.92 g/cyl.

Good info here too on the changes to get enabled:
