In the doumentation at https://www.balena.io/fin/docs/developers/ I saw we can disable HDMI for power saving purposes.
We would like to disable both that and USB for security reasons (i.e. prevent people from using a dashboard for logging in locally, plug in rogue devices etc.).
- Is this possible (without disabling other hardware, such as network/wifi interfaces)?
- Can enumeration of devices be prevented?
- Any difference wrt using Raspbian vs BalenaOS?
Love the device, BTW, thanks for all the effort!
