Setting Manual Exposure and list of available options for nvarguscamerasrc

thanks but can you please help me achieve the same result of: 3. Basic Recipes — Picamera 1.13 Documentation

basically i need to set the ISO to 800 or raise the gain and turn off auto exposure, i have tried below but it didn’t work, the image is too dark because the exposure is locked at camera startup

gst-launch-1.0 nvarguscamerasrc ispdigitalgainrange="14.72 14.72" gainrange="14.72 14.72" aelock=true ! 'video/x-raw(memory:NVMM),width=1024, height=768, framerate=120/1, format=NV12' ! nvvidconv flip-method=0 ! nvegltransform ! nveglglessink -e

also note that previously in nvcamerasrc you had auto-exposure parameter available, but now in nvarguscamerasrc that parameter is not available.
