Spotlight services not fully stopping

I wish to have all spotlight services stopped on my MacBook, however with turning all options off in the settings and also the "Help Apple Improve Search" option, however the option turns back on whenever there is a restart on the laptop as well as background services running. How can I disable this permanently? I have tried to following as well:

sudo mdutil -a -i off
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
sudo launchctl unload -w /System/Library/LaunchAgents/com.apple.metadata.mds.user.plist
sudo rm /Library/Preferences/com.apple.spotlight.plist
sudo launchctl disable system/com.apple.metadata.mds

However with ps aux | grep -E "mds|Spotlight|corespotlightd" it still shows spotlight related services running:

What else can I try in order to stop these and to stay shut off after turning my laptop on and off again?
