Does anyone know how to prevent a single board computer from always displaying a logged in terminal through the onboard HDMI port on boot? (lemmy.ml)

I have a Tinker Edge T as a server, and it's running Mendel Linux which is a default debian-based OS recommended by the manufacturer. One thing I really don't like is the fact that if you plug in an HDMI cable and USB keyword, it will always give you access to a terminal as the default user with no authentication prompt or anything else, and it doesn't even need a password to become root either. Is there a general Linux way to set a password for the GUI like you can on regular desktop Linux, or otherwise require authentication before you get a terminal or any other functionality, so someone can't just plug an HDMI cable and keyboard into the device and have root access to the entire device?

Idk much ablout Mendel Linux. Is there a getty@tty1.service service running in systemd? You could disable or edit that. Or take a look at /etc/default/grub see if they added something to the kernel cmdline.

Try this.

I searched on how to disable auto login without a desktop manager.
