Turn off engine auto stop/start? 2021 Yukon Denali

[yahtzee]

Can it be done permanently? It's so annoying, especially for such a large engine. I get that I can push the button every time I get in but does anyone know if I can just disable?

I don't think anyone has one for the 2021 Tahoe/Yukon yet.  The bigger problem is that they are on the new electrical architecture now called VIP or Vehicle Intelligence Platform.  This system has a vast amount of changes over the Global A architecture that GM has used since 2009, and its got a lot more sensitivity towards foreign interference.  

 

I'd stick with the button if I were you for now.
