This has been a topic of discussion going back at least 6 years. The short answer is it would be very difficult to add support, and nobody has done it. The long answer is at the link.

> The idea primarily is intended for supporting a "wireless" setup for the hotend/…extruder, so that most of the wires are coming from a secondary board instead of the primary board. with ESP32 we can pretty much just hook up a couple of mosfets and stepper driver to decouple the hotend/extruder electronics, leaving just the power cable required.
