The short answer is no; policies like that are enforced by algorithms, not by humans with "wiggle room."
The longer answer is: why do you want it to be free in the first place? Free courses usually just attract trouble. They made it harder to create free courses for a reason - they attract pirates, students who don't engage, and often negative reviews from trolls who have nothing better to do. And since you can't send promotional announcements to free students, it's not a great strategy as a promotional tool anymore either.
You can however still use a judicious amount of carefully-sent free coupons to promote your course, even if the course itself isn't free.
