If you have a DIC on your Tahoe, I believe that all of the options contained there involve changes in the BCM settings.

The tech2 is a diagnostic tool for the most part, you can't really "modify" things with it other than the afterblow as mentioned already. If you have the digital HVAC control you can make the outside temp display on the HVAC control panel and you can adjust tire size.
Those are the only "user" adjustable things that I am aware of. The rest is all test functions and relearn various modules/sensors, and lastly calibrations as a pass thru device if that is even still supported by techline anymore, some have reported it takes special access by gm support.

Afterblow, NBS, NNBS, DIC, etc. Manufacturer specific anachronyms that all the long term owners are used to. We forget these vehicles are lasting 2-3x as longer than GM expected and some of these $86k vehicles are being sold for $14.5k (that’d be my Esky lol), and still reliable with another 200k left in them.
That’s a solid referral on the BTdieselwork OBD programer. 295 for the unit and 395 for the version with the engine & trans tune, which I regret not getting.
The best way to get up to speed on the Tech2 is you tube videos. All of GM’s secret unlock features are found in the BTdieselwork module.

The pathing can be very vehicle dependent, so not all selections may be valid for yours. YMMV
