How to set the setAeRegion using the nvarguscamerasrc pipeline

I currently have this gstreamer_pipeline:
gstream_pipeline = (
“”"
nvarguscamerasrc ! video/x-raw(memory:NVMM),
width=(int){width}, height=(int){height}, format=(string)NV12,
framerate=(fraction){framerate}/1 !
nvvidconv flip-method={flip_method} !
video/x-raw, width=(int){display_width}, height=(int){display_height}, format=(string)BGRx !
videoconvert !
video/x-raw, format=(string)BGR ! appsink
“”".format(
width=args.capture_width,
height=args.capture_height,
framerate=args.framerate,
flip_method=args.flip_method,
display_width=args.display_width,
display_height=args.display_height)
)

is there a way to set the Auto Exposure Region?

Check the nvarguscamerasrc cap by gst-inspect-1.0 nvarguscamerasrc to get those information.

exposuretimerange="34000 358733000"

Thank your for the tip, but I see nothing relating to the ae ROI. Is setting the ROI only possible from code?
