By using policies, you can set mandatory (managed) and recommended preferences for the Chromium browser. Mandatory preferences define fixed values that cannot be changed by the user. Recommended preferences define default values that can be changed by the user. For further information, see https://www.chromium.org/administrators/.
Use the Scout feature Files configured for transfer to transfer policy files (.json) to the required target directory on the device:
Fixed values /setup/chromium/managed Default values /setup/chromium/recommended
For further information, see Files configured for transfer.
