If I signed a separation agreement with my employer, can I forward evidence of wrongdoing to my former empoyer regarding my supoervisor?

In Jnue of 2018, I signed a separation agreement with the University. I was falsely accused of something by my supervisor and decided not to fight it and leave.. However, there is now a harassment and discrimination, lawsuit against the same University and supervisor by other members of the staff and former student-athletes. I feel obligated to submit a report to the University OEE office revealing what I know about the actions of my former supervisor. My agreement states: "Rizzi agrees that he will not, at any time, make any statements, written or oral, or post or issue any statements, comments, or other communications or information on any social network or through any social media (such as Facebook, Twitter, or blogs), whether anonymously or not, that disparages, defames, or reflects reflects negatively on any of the University’s officers, or that tends to injure the business or reputation of the University, or any of its officers or employees.." Can I do this?
