stm32g474ve , dma can be triggered using external interrupts, but dma cannot be triggered using software.
In theory, both external interrupts and software interrupts should trigger events. At the same time, I have verified that stm32h750 is OK.
So I want to know what I didn't think about.

It is not clearly stated what you have done, observed, and expected.
DMA can surely be triggered by software, see STM32CubeG4/Projects/NUCLEO-G474RE/Examples/DMA/DMA_FLASHToRAM at master · STMicroelectronics/STM32CubeG4 (github.com)
