Not exactly sure how they do safety/emissions in NJ, but everywhere else that I know of merely plugs in the OBDII to check for current MIL/CEL illumination and stored codes. No codes = pass.
As far as the EGR bit goes, the ECU can be tuned to *not* check for EGR operation, thereby not throwing (or storing) a code. This can be done via commercial vendor (GDE) or via the DIY ECU tune for the cost of a specific OBDII dongle. Legal to the letter of the law? No - which is why everyone says "for offroad use only". Will the emissions scanner pick up that your ECU has been retuned? Also "No". (Seriously, we should start calling this the "VW factory mod")
I can't fathom that NJ is doing anything different than the other states when it comes to testing for emissions compliance.
HISTORY: Many on this board have been doing this via SEGR, DIY Tune, or GDE for many years. All effectively render the EGR inoperable and incapable of throwing a code. Many of these people live in emissions-tested locations (Northern Virginia, for me). I do not know of a single reported instance of someone failing an emissions test b/c the EGR was discovered inoperable by one of these methods. (Anyone?)

No it won't harm it. Anymore miles that the egr is active is causing harm potentially. I see your in Joliet, il. I'm about 100 miles south. Why do you need inspection?
Did you mean me? I live in jersey. Inspection is mandatory here and it's 150 dollars per time I get pulled over.
