Can I work side jobs on a OPT STEM Extension

I am currently on an F1 OPT STEM Extension working for a video production company. I have been offered to do some side work acting which still falls under my STEM major of Digital Communications. However I am not sure if working a temporary job will violate my OPT STEM status.

It would mean I would need to file a W9 taxpayer information form for each side job that I get, which I imagine would be a red flag if my social security number is being flagged up from multiple employers. (If that’s how it works)

If any one could help or knows of a way to make this possible please let me know!

Thanks guys.

Yes, you can hold multiple jobs during your OPT and go beyond 40 hrs. You need approval and I-20 for all the jobs from the university.
