These prints are hardcoded in the source file of the camera module gstnvarguscamerasrc.cpp as explained here . The following commands can be used to disable these hardcoded messages and compile the module.

make
sudo make install
You may also use the following line to disable opencv warnings. It is also best to restart nvargus-daemon service each time before using the camera:
import warnings
warnings.filterwarnings('ignore')
import sys, os
os.system("sudo systemctl restart nvargus-daemon")
os.environ["DISPLAY"] = ":0"
os.environ["OPENCV_LOG_LEVEL"] = "OFF"
This will allow you to run your script without any warning messages:
