text: Title: Does tracking mode support NMS threshold?
  Body: ### Search before asking
  
  - [x] I have searched the Ultralytics YOLO [issues](https://github.com/ultralytics/ultralytics/issues) and [discussions](https://github.com/orgs/ultralytics/discussions) and found no similar questions.
  
  
  ### Question
  
  I'm currently using YOLOv10 to track some objects and there are a lot of cases when two bounding boxes (of the same class) have a high IoU, I tried setting the NMS threshold ("iou" parameter) of the tracker very low it but doesn't change anything... I also tried setting a high NMS threshold (expecting a lot of overlapping BBs) but no matter what value i set, the predictions/tracking looks the same.
  
  I tried to search about the parameters of the YOLOv10 tracker on the Ultralytics Docs and on Ultralytics GitHub but couldn't find anything about the NMS Threshold on the tracker. Is it implemented? Is the parameter name "iou" similar to the predict mode?
  
  Can someone help me in this regard? Thanks!
