Infotainment radio "off" screen

[wezlz]

I just picked up my 2021 Sierra SLT last week, and I'm still learning the truck. I noticed when the radio is off and you start the truck, the red GMC logo appears on the infotainment screen. The home button brings up the icons and such. When I go to turn the unit off. I press and hold the power/volume button to turn the unit off it goes to a plain blank screen. I was wondering if there is a way to put the GMC logo back up on the screen, or something for that matter. Instead of just being blank grey.

[Thankful]

No, it's not possible.  The only way to make it possible would be to pay GM to reprogram the unit, but I doubt they'd do it.
