Driver configuration and display pin-out must be verified, this board uses the GD32F303 RET6 SoC, it could be compatible with the STM32F103 as in other boards with the same SoC.

Seems that MS35774 driver is a clone of the TMC2208, **TMC_UART** configuration was found only for X, Y and Z drivers, so maybe E0 is working in TMC2208_STANDALONE mode.
Based on the disclosed board configuration, images and Creality's printer.cfg
It may be, although this is labeled as GD32F303... so if it follows the same numbering as STM32 the MCU is a Cortex-M4 instead of a Cortex-M3, so it may have a few more built-in ports and capabilites. In any case, it's very fast! 168 megahertz is fast enough to outrun even the bigger imperial cruisers. |

It is a Cortex-M4 at 120MHz https://www.gigadevice.com/product/mcu/arm-cortex-m4/gd32f303ret6 |
Aha! Probably can still outrun most tie fighters. |
Maybe even Tie interceptors and close to the USS Defiant. |
