Disable Anchor Presets on Driven RectTransform?

I'm using DrivenRectTransformTracker in a script to drive the min/max anchors of the RectTransform to which the script's attached, and I haven't found a way to disable the anchor presets in the RectTransform's inspector. I've tried these combinations of DrivenTransformProperties, among others:

 rectTracker.Add(this, rectTransform, DrivenTransformProperties.Anchors);
 
 rectTracker.Add(this, rectTransform, DrivenTransformProperties.All);
 
 rectTracker.Add(this, rectTransform, DrivenTransformProperties.AnchorMaxX | DrivenTransformProperties.AnchorMaxY | DrivenTransformProperties.AnchorMinX | DrivenTransformProperties.AnchorMinY);

I'm able to disable the Min/Max float fields with these, but that doesn't seem to be of any use if the presets are still active ... Also I've just noticed I can still click and drag the anchor gizmos in the scene view, too. I don't see the point of driving anchors by a script if they can still be modified in the editor. Hopefully I'm missing something. Does anyone know of a way to completely lock the anchors for a RectTransform, sort of like Canvas components do (I don't want all the properties driven, though. Just the anchors)?

Thanks!
