STM32MP1 I2S on M4 core

Hi, I want to use the M4 core to handle all Audio DSP work

I can see that MXCube allows the SAI ports to be enabled on the M4 core

But it appears the I2S ports are not.

I am Missing something here

Unfortunately the Pins I need to be the PZ0-1-2-3 as PCB is done

Else If Its only possible to use the I2S from the Linux A7 then is it even possible to transfer audio data between the cores?

Thanks
