Setting PA/LNA pins on port 1 results in NRF_ERROR_INVALID_PARAM

SoftDevice: S113 v7.0.1

SDK: 15

Chip: nRF52840

It looks like setting PA/LNA pins on port 1 result in NRF_ERROR_INVALID_PARAM being returned by sd_ble_opt_set().
When PA/LNA pins are set on port 0, the problem does not exist.

I can't find such a constraint anywhere in the documentation. I need PA/LNA pins on port 1 because I use u-blox BMD-345 module.

Please advise.

My code:

void Amplifier_Init(uint32_t pa_pin, uint32_t lna_pin)
{
    Amplifier.is_init = true;
    Amplifier.pa_pin  = pa_pin;
    Amplifier.lna_pin = lna_pin;

    nrf_gpio_cfg_output(Amplifier.pa_pin);
    nrf_gpio_cfg_output(Amplifier.lna_pin);

    uint32_t eep = (uint32_t)(&NRF_RADIO->EVENTS_READY);
    uint32_t tep = nrf_gpiote_task_addr_get(AMPLIFIER_GPIOTE_SET_TASK);
    nrf_ppi_channel_endpoint_setup(AMPLIFIER_PPI_SET_CHAN, eep, tep);
    nrf_ppi_channel_enable(AMPLIFIER_PPI_SET_CHAN);

    ble_opt_t opt;
    memset(&opt, 0, sizeof(ble_opt_t));

    opt.common_opt.pa_lna.gpiote_ch_id        = AMPLIFIER_GPIOTE_IDX;
    opt.common_opt.pa_lna.ppi_ch_id_clr       = AMPLIFIER_PPI_SD_SET_CHAN;
    opt.common_opt.pa_lna.ppi_ch_id_set       = AMPLIFIER_PPI_SD_CLR_CHAN;
    opt.common_opt.pa_lna.pa_cfg.active_high  = 1;
    opt.common_opt.pa_lna.pa_cfg.enable       = 1;
    opt.common_opt.pa_lna.pa_cfg.gpio_pin     = pa_pin;
    opt.common_opt.pa_lna.lna_cfg.active_high = 1;
    opt.common_opt.pa_lna.lna_cfg.enable      = 1;
    opt.common_opt.pa_lna.lna_cfg.gpio_pin    = lna_pin;

    // FIXME: this fails with NRF_ERROR_INVALID_PARAM
    uint32_t err_code = sd_ble_opt_set(BLE_COMMON_OPT_PA_LNA, &opt);
    NRF_STATUS_CHECK(err_code);
}
