Do cars in New Mexico require a catalytic converter?
All vehicles registered in, or commuting at least 60 days into, Bernalillo County are required to pass an emissions test every two years.

Outside of Bernalillo County, state or local laws do not (as far as I know) require catalytic converters, but Federal law may prohibit you from removing your cats from your vehicle. Federal law requires all cars as built after 1975 to be equipped with a catalytic converter.
Can replacing the flange gasket to exhaust manifold clear a p0420?
Not likely because: Code p0420 refers to a problem with your catalytic converter. The engine computer is able to test that converter by using an oxygen sensor before and after the converter. The computer can only test the converter under very specific driving conditions. If the computer determines that it is a good time to test the catalytic converter it will run the test. It compares the oxygen sensor readings in front of the converter to the readings behind the converter to see if the catalytic converter is functioning properly. If it is not functioning properly it will trigger a p0420. Sometimes if a catalytic converter is on the virge of failing it may fail one test and pass the next. This will cause your check engine light to come off and on every once in a while when the test is performed.

Normally when catalytic converters become clogged and need replacing there is a reason for this. Something caused the converter to become clogged.

If the check engine light is not on and the vehicle is running perfectly with the new converter then it will more than likely pass the smog test.
