DUI in NJ and background check impact?

Basically i have been interviewing with a large bank that rhymes AB Borgan. I have a minor criminal record that they are already aware of and are not deterred by seemingly. Unfortunately for me, through my own poor decision making, i picked up a DUI charge in NJ a few weeks ago after having already disclosed the prior history. My question is will they find this DUI charge/potential conviction as well? It’s in NJ which does not classify DUIs as criminal but instead traffic offenses. Ive had a lot of great conversations with this person at this point and have already gotten past disclosing some of the things that have happened in my past mainly from my college years. Now i have this dui which im greatly embarrassed and ashamed about. I dont really want to disclose it happened and am wondering will they discover if it wont show on a criminal background check. Thanks for any feedback. Committed to never having to deal with bullshit like this again that was easily preventable but i am here and now just asking for any advice.
