I just greased our new 2021 Chevy 3500 for the first time at about 2,000 miles on the clock. I assumed that the 9 front end grease zerks would have been greased either at the factory or dealer during the PDI, my assumption was wrong. All nine fittings were perfectly free of any sign of grease and all took between 5-7 pumps to slightly push the rubber boots out. My 2018 took only 1-2 pumps for the grease to pop and slightly push the boots out. The greased steering components are absolutely identical between the 2018 and 2021. Ungreased new HD trucks seems to be a very common complaint on other internet forums.
If you have a new GM HD truck.... you ought to get it greased!
edit: I added a thread with pictures of each zerk and some commentary.
