turn off constant notification messages

[Blake989]

2018 Yukon Denali. Every time I start it, every time, I get a barrage of notification messages "power running boards are turned off", "blue tooth device connected", etc... I DO NOT CARE. They eventually go away, or I can hit the "check" button every time for each warning, but have any of you guys figured out how to turn these off, permanently? I've read the owners manuals, and assume the instructions are buried in there some where, but I cannot find anything....
