Do you want to disable automatic updates for this application?
Warning: To re-enable this requires direct api calls,
see https://balena.io/docs/reference/api/resources/device/#set-device-to-release
Alternatively you can pass the --pin-device-to-release flag to pin only this device to the selected release.

Preload a balena application release (app images/containers), and optionally
a balenaOS splash screen, in a previously downloaded balenaOS image file (or
Edison zip archive) in the local disk. The balenaOS image file can then be
flashed to a device's SD card. When the device boots, it will not need to
download the application, as it was preloaded.

your shell environment. For more information (including Windows support)
