I contacted the program director regarding this requirement and she recommended a course through ed2go, and it’s the course I chose to take! There’s another course through coursera that she said was acceptable, but hadn’t had any previous students take before.
here are the links for both courses: https://www.ed2go.com/courses/business/communication/ilc/fundamentals-of-technical-writing
https://www.coursera.org/learn/technical-writing
Let me know if you have any questions about the ed2go one!
