The car/ECM has no "clue" if the EGR is work or not, open or closed.
You can:
*Unhook and plug the vacuum line that actuates the EGR
*Remove and block off the EGR flange
*Drill the headers, weld in a pipe to carry the exhaust gas to the EGR and keep it functional.
Eliminate of the EGR MAY result in part throttle pinging and necessitate a recurve of the timing (ECM tuning), but probably not.
