Object Tracking Training: Objects to avoid

I'm working on training an object tracking model in CreateML for visionOS that has fan blades on it and looking to try to train while ignoring a section of the geometry. When I train currently, it can detect the object if the fan blades are in the same orientation as when scanned but if they move it struggles.

I see there is an "objects to avoid" data source that can be added but upon reading the description, I don't think it does what I'm needing but I could be wrong. Is there anyway to have the training ignore a part of the geometry that has a significant effect on the silhouette of the object?
