Problem with starting my program automatically after system startup

hello.
If so, the content in the link below seems to be the same problem as mine.
Does that mean adding the command line to /etc/systemd/nv.sh doesn’t work?

How to start the program automatically at After system startup？（JetPack4.4.1）

I want my program to automatically start after system startup 1.But there has no “rcs” file under the directory： “/etc/init.d/”，and it doesn’t work after I create the rcs file； 2.I user the command to add autostart.desktop file which is “gnome-session-properties” ，it successfully generated the bootstrap file(.desktop) under the directory “.config/autostart/”,but it doesn’t work either.
