If the o2’s are disabled, it will show they are not functioning when they check emissions readiness. Most states allow a max of 1 “not ready” OBD readiness monitor but that 1 is typically reserved for catalyst (since you’re catless). The oxygen sensor may put you over.

You should google area 74 o2 simulators. I used those on my n52 coupe and was able to pass emissions. It would occasionally trip a CEL when I did WOT runs but it did the trick for emissions.
