2018 GMC Terrain Denali 9 speed automatic tuning

Have searched and found no definitive answers here. I am working on a 2018 GMC terrain denali with the 9 speed transmission. HP site does not list it as supported controllers, and when I try to gather info before I read it, the editor does not pick up the TCM. None of the options in the hardware drop down box were a match for the TCM/trans type. Can these transmissions be tuned at all on these vehicles with HP tuners? If so, what do I select for hardware to read it?

Thanks in advance!
