Periphery Bit for P0420 Code

Does anyone know the periphery bit to disable the P0420 (cat efficiency) code?

I did not see it in the periphery2 (FCA) table.

^Thank You

I had already seen the 2nd link but the first one helped, the information I actually needed was in the "periphery configuration" portion of the 1st link.

I'll get right on this.

Ok, did the FCA bit change from 1 to 0
did the OBD availability & pass changes

drove 40 miles, mixed highway and street, a few hard pulls
no CELs so far.
