What overhangs are you talking about? Perhaps you could post a picture so I can try to improve the issue. It's difficult otherwise as my print had no issue in that regard.

Basically, the round helical design makes it so that there is a little bit of visible overhangs. Not an issue but would look prettier if there was no inconsistencies visible.

Mind sharing an image with an arrow to what you are talking about? What would you do to improve the print profile or model? Supports would not help and when I look at it’s amazing that we can print such stuff these days. I see no overhang issues.
