Alpha-N Tuning

I?m looking at HP Tuners for tuning a 2019 Silverado (L82) with a 6L80 and had some questions.

Firstly, can the E92 ECU be tuned using Alpha-N, e.g. RPM vs TPS? If so, how is this done within HP Tuners?

Second, does HP Tuners support auto-tuning the fuel tables with a wide-band o2 sensor; e.g. supplying a target air-fuel ratio, running the vehicle on a dyno and then the software auto adjusts the required parameters to meet the commanded air-fuel ratio? If so, how would this be done within HP Tuners?

Lastly, regarding the 6L80. Can it be programmed to hold any selected gear in any situation; e.g. no down or up shifting unless commanded by the TUTD controls, 2nd gear starts at WOT, etc? If so, how would this be done in HP Tuners?
