2012 O2 sensors not ready. Emissions

Hello thanks in advance.
2012 5.3 o2 sensors won’t get ready for emissions. Replaced all of the o2 sens. Drove 300 miles multiple times. Any input?

Had that happen with my 2002 Chevy Camaro. Had to drive 200 miles until it was ready to be smog tested, but I didn't have to change the O2 sensors. It passed smog easily after that.
