Setting for turning CNC cutouts to dust?

Is there a setting to turn this function off ? I have a a big project and do not want to modify all my tops to stop this. Example below , I just need to cut out the hole in the sub top not go around it until it all turns to dust. While I am at it , is there a setting to keep the parts from being placed on a angle on the sheet. I have turned the true nesting slider up and down but it does not change this. Thanks
