Receiving CAN messages via DMA on a STM32H7

I'm wondering whether there is a DMA channel to transfer a received message from the CAN fifo to a memory location. 

Is it possible at all to get DMA working with the CAN controller?

Kind regards,

Stefan

RM says the DMA / MDMA cannot access the reserved FDCAN 10kB SRAM.

But I'd be happy if you find out that this is possible.
