How disable dma on fmu pins

Hi
Someone understands how to deactivate the dma on the FMU pins, I have a pixhawk 4 and ardurover 4.0. I need to use the fmu pins 7 and 8, to put some relays, but to what I understood in the documentation to use it I need to disable the dma in those 2 pins, but I have not managed to understand how to do it

thanks for you help.

You can put relays on Auxout5 and Auxout6 without changing any parameters or source code.

thanks amil is solved, it was my mistake, when interpreting some things
