Unable to control P0.30 on nRF9160

This is not specifically a Feather issue, more of a SDK usage issue I believe.
Using SDK v1.9.1.
I am using the following code, but am unable to control in P0.30 (D3 on the silkscreen).
I can control P0.29 and P0.04 with this below code without issues.

As opposed to most other gpio, I think this one is on PORTD instead of PORTC, could it be that PORTD is not powered up for some reason and I am missing that?

The below code is copy/paste from a larger project so hopefully I did not forget any details, but this is the idea.

#include <zephyr.h>
#include <stdio.h>
#include <stdlib.h>
#include <drivers/gpio.h>

// Feather Pin (D2) 29 = SD_SWITCH (output, active low, nRF9160 connected low)
#define SD_SWITCH_PIN                 30 // pin D3
#define SD_SWITCH_PIN_NAME            "GPIO_0"
#define SD_SWITCH_BIT                 BIT(SD_SWITCH_PIN)

void main(void)
{
    const struct device *gpio_dev;
    uint32_t gpioValue = 0U;
    int err;

    const char* const gpioName = SD_SWITCH_PIN_NAME;
    gpio_dev = device_get_binding(gpioName);
    if (!gpio_dev) {
        LOG_ERR("Cannot bind gpio device");
    } else {
        err = gpio_pin_configure(gpio_dev, SD_SWITCH_PIN, GPIO_OUTPUT_ACTIVE);
        if (err) {
            LOG_ERR("Cannot configure SD_SWITCH_PIN gpio");
        } else {
            printk("SD_SWITCH_PIN gpio configured\n");
        }
    }
    enable_gpio();
    while(1);
}

void enable_gpio(void) {
    const struct device *gpio_dev;
    const char* const gpioName = SD_SWITCH_PIN_NAME;
    gpio_dev = device_get_binding(gpioName);
    if (!gpio_dev) {
        LOG_ERR("Cannot bind gpio device");
    } else {
        gpio_pin_set(gpio_dev, SD_SWITCH_PIN, 0);
    }
}
