Greetings @A_M,
If you want to install a package to the base TorizonCore OS outside of a container, then you’ll need to re-build the OS image with Yocto as described here: Build TorizonCore from Source With Yocto Project/OpenEmbedded | Toradex Developer Center
You can then add whatever packages you want to the base OS. We can also consider adding it by default as a request, though these can take a while for our team to process and there’s no guarantee we will accept the request.
Best Regards,
Jeremias
