If you remove the sensor, that will be a (small) place for the engine to breath if the converter is plugged. So remove the entire sensor from the exhaust.
Keep in mind, there will be an exhaust leak there. If it is proven that the converter is plugged, I don't recommend any distance driving. Honestly, they make universal converters. You basically cut the old one off and replace it with the new and clamp it in place.
Also, without the sensor, the computer has no idea as to how much fuel the engine needs to run. As a result, it goes into what is closed loop providing as much fuel as it can to run the engine.
One last thing. If the converter is plugged and getting red hot, like most do when plugged, they are EXTREMELY hot and can cause a fire.
Let me know if you have other questions. Thanks for your service to our country. Many of us still appreciate it!
