Apt and mount commands not found Verdin IMX8M plus

I can access the flash from the container but what I’m trying to do is shutdown /reboot the unit from the container. I was trying to use the scripts from here Shutting down the the Apalis SoM from inside a docker container - #4 by Juzujka so I wanted to access the flash from the Torizon OS - because I need to copy the wait_for_shutdown.service file to /etc/systemd/system. I think.
