yeah you could, I had it that way for about 1-1/2 years. You'll need to plug off the header side and the side at the EGR valve, leave the sensor alone and leave the vacuum connection on the sensor open to the air, but leave the vacuum hose on the EGR diaphram. I think it was 22mm brass plug for the valve side, I had the header welded shut.
