Since the Roon Control component has the user interface, and the user interface depends on OpenGL version 3.0 as a minimum, I think you’re out of luck. From a Roon Labs post on hardware requirements:
The user interface is driven by a piece of technology that could be best described as a game engine. It supports fluid animations, and we are trying to keep the frame rate at 60 frames per second (fps), just like a game. It renders graphics using OpenGL and hardware acceleration, just like a game, too.
