Selective Tile Rendering using Blender CLI?

Is there a way to render a specific set of tiles in the blender’s command line?

I know we could use the ‘blender -P <script_file>’ option and do this using a external script file. But, is there a way to do this directly in the command line itself?

I was talking about rendering a single frame across multiple machines using Flamenco on blender.chat (#flamenco). But, looks like we can’t do that yet. Developer (Sybren A. Stüvel) there said, it’s preferred not have any python scripts directly on the command line.

For questions on how to use Blender, please use the community website:

This is just not supported without a Python script.
