Custom Data Conectors not available

Hi a-simarg,

According to your description, my understanding is that you want to enable the Custom Data Conectors on PowerBI Desktop.

Using Custom Data Conectors doesn’t require enabling it in Preview Features now, to load extensions during development, we will need to lower the security level for extensions in Power BI Desktop to enable loading unsigned/uncertified connectors.

1. Go to File | Options and settings | Options
2. Go the Security tab
3. Under Data Extensions, select Allow any extension to load without warning or validation
4. Restart Power BI Desktop

For more information, please refer to this blog: https://github.com/Microsoft/DataConnectors

Best Regards,

Teige
