Can't override pin assignment in .overlay

[BENBF]

Hello,

I'm trying to declare custom GPIO on pin that are already used by the default dts of the nRF7002-DK. I'm currently testing on P0.11 that is used by SPI4.

My code is quite simple and toggle a LED, a custom GPIO no used by default and a custom that is already used by default. Only the two firsts are effectively toggling, the custom GPIO that is used by default remains at 0. I tried with several pins and the result is always the same.

My code :

#include <zephyr/kernel.h>
#include <zephyr/drivers/gpio.h>

#define GPIOCUS0 DT_ALIAS(gpiocus0)
#define GPIOCUS1 DT_ALIAS(gpiocus1)
#define LED0_NODE DT_ALIAS(led0)

static const struct gpio_dt_spec gpioTest = GPIO_DT_SPEC_GET(GPIOCUS0, gpios);
static const struct gpio_dt_spec gpioTest1 = GPIO_DT_SPEC_GET(GPIOCUS1, gpios);
static const struct gpio_dt_spec led = GPIO_DT_SPEC_GET(LED0_NODE, gpios);

void main( void ) {

	gpio_pin_configure_dt(&gpioTest, GPIO_OUTPUT_ACTIVE);
	gpio_pin_configure_dt(&gpioTest1, GPIO_OUTPUT_ACTIVE);
	gpio_pin_configure_dt(&led, GPIO_OUTPUT_ACTIVE);

	while(1){
		gpio_pin_set_dt(&gpioTest, 1);
		gpio_pin_set_dt(&gpioTest1, 1);
		gpio_pin_set_dt(&led, 1);
		printk("ON\n");
		k_msleep(500);
		gpio_pin_set_dt(&gpioTest, 0);
		gpio_pin_set_dt(&gpioTest1, 0);
		gpio_pin_set_dt(&led, 0);
		printk("OFF\n");
		k_msleep(500);
	}	
}

My overlay file :

/{
    gpioCustom{
        compatible = "gpio-keys";
        gpioCus0: gpioCus0{
            gpios = <&gpio0 11 GPIO_ACTIVE_HIGH>;
            label = "Custom";
        };

        gpioCus1: gpioCus1{
            gpios = < &gpio0 26 GPIO_ACTIVE_HIGH >;
            label = "Custom2";
        };
    };

    aliases{
        gpiocus0 = &gpioCus0;
        gpiocus1 = &gpioCus1;
    };
};

/delete-node/ &spi4;

Has anyone got stuck on a similar issue or im I missing something somewhere ?

Thank you
