Are you referring to the "Developer" license level? If so, everything is enabled when it is "Developer" mode. This is discussed in our Guide: License your app—ArcGIS Runtime SDK for Qt | ArcGIS for Developers
Here is an excerpt from the above link:
You can download and install an ArcGIS Runtime SDK using an ArcGIS for Developer account. You then have access to all of the functionality in the API for development and testing purposes. In this mode the app will adopt the following behavior:
- Any map will be watermarked with the words Licensed For Developer Use Only (as pictured here).
- A message will be written to the console or log that states that the app is Licensed For Developer Use Only.
