CubeMX doesn't support this directly, but it can be done in your own code.

Here is one post of many:

I use stm32l4xx, instead of the HAL_PCDEx_PMAConfig() functions, I use the HAL_PCDEx_SetTxFiFo()/HAL_PCDEx_SetRxFiFo() functions. Could you tell me how to configure them correctly for Composite USB? Thanks in advance.
