YOCTO : How can I exclude drivers that are reserving and handling my embedded board GPIO

I am using SAMA5D27-SOM1-EK1 embedded board. I used YOCTO project to build Linux Operating System.

When I show up the list of GPIOs existing on my board, I see that some of them are " USED ". Searching the net I found that the reason they are used is that there are some drivers / modules are handling that GPIOs.

So I opened the Linux kernel MENUCONFIG and I DISABLED some features like " GPIO BUTTONS " , " LED SUPPORT " .. and I re-build the kernel.

But the same issue comes out: the GPIOs are still used.
