I don't see any O2 sensor diagnostics being turned off in your file.
o2 sensors no, but you're being pedantic. You know that 90 percent of people that want "Lambda off" are asking for cat removal, and that's exactly what this file did.
MAF threshold for catalyst diagnosis (minimum) ip_maf_min_cat was changed to higher than possible values.
MAF threshold for catalyst diagnosis (maximum) ip_maf_max_cat was changed to lower than possible values.
In effect, the conditions to diagnose the catalyst will never be met.
41E9C and 41E9D lc_ls_down_obd_2_man_deac should disable all OBD diagnosis of the rear sensors as well if needed.
This is not how I'd have done this, but it works.
