How to set MFX GPIO10 pin for SD card detect if it doesn't show up in pin configurator?

[repairman]

I am working with the ST32F769I evalkit and am trying to configure SDMMC1 and FatFs. The SD card needs the detection pin to be set, which is MFX GPIO10 according to the docs. This appears to be a pin on the slave MCU if I understand correctly, so how can I set this pin in the configurator? Is it sufficient to choose an available GPIO pin and set that as Detect_SDIO? Is that the same as/does it take care of setting up SD detect? I have seen on other boards that the SD_Detect automatically shows up as an option in the configurator for FatFS config, but only Detect_SDIO shows up when using this evalkit. Thanks!
