V8 to 4 cyl mode

how do I turn off the V8 to 4 cyl mode on a 2008 5.3
also how do turn off the traction control for good.

As simple as -
{B0921} Active Fuel Management Option, set to No

On the traction control I am not sure, that is usually not a direct ECM input, it goes via the BCM or ABS maybe.

So I need a license to shut off the active fuel management ? shut this
