Remove initial stroke of ofPath?

Hi, I would like to draw a donut shape that can toggle between filled and unfilled.

I could make the filled donut shape using ofPath but if I unfill the shape, and set the stroke width, a line appears and I would like to remove this line if possible.

Here’s my code and the resulting image below.

ofPath circle;
circle.setFilled(false);, ofGetHeight()/2, 100);, ofGetHeight()/2, 120);


Thank you in advance.
