STM3N6: CubeMX pin conflicts (false positives)

Hi all, 
I am trying to get a zephyr project running on an STM32N6570-DK, including Camera, NPU, VENC and Ethernet.

I have been using STMCubeMX 6.16.1 to create the project based on the provided DK default settings.

For the Ethernet block, the configurator shows pin conflicts, I double-checked and the pins are not in use by the Ethernet driver:

There are similar warnings for the SD/MMC2 block:

Am I missing something here or can it safely be ignored?

These can be safely ignored. The presentation isn't the best, but the UI is telling you that some things can't be enabled because some pins are in use. But there is no error with the current settings.

If you open the dropdown, you will see only some settings within there have issues.
