Well that’s a bummer. Was going to be my path with my new at4 6.2
Help: Does the 6.2L have Fuel Management (AFM/DFM)?

My 2021 Yukon Denali 6.2L owner's manual has this short section on "Dynamic Fuel Management" How do I tell "if equipped"?

They never skipped the DFM on the SUV’s, only some of the pickups. All of this gen Tahoe/Yukon/Esky/Suburban/XL/ESV got DFM
