ESP32 SOFTWARE SERIAL USE

It's possible to use up to 8 drivers with the ESP32 using 2 hardware serial and TMC2209 which can be set to differing UART addresses.
But because the esp32 only has 3 UARTs, one for usb, you can only connect two TMC2208s, is it possible to connect more using software serial?

I noticed that in the datasheet there is explained a method on how to use more than 4 drivers in single UART port.

That'd seems like a fun challenge to make it work with marlin
