I dont have a stm but a GD (giga device) 4.2.2 board how do I tell that to the builder ? seems kinda important if its a different cpu/mcu?

I have the GD32F103RET6 on my 4.2.2 ender Neo.
I Build with #STM32F103RE_creality_maple in Auto Build Marlin. It now compiles and loads perfectly. Other versions would compile but not boot all the time.
