It’s been a while since this code has been tested, but here is what I last used.

int Ublox::enableNAV_VELNED()
{
    unsigned char gps_nav_velned[] = {0xb5, 0x62, 0x06, 0x01, 0x03, 0x00, 0x01, 0x12, 0x01, 0x1E, 0x67};
    int gps_nav_velned_length = (sizeof(gps_nav_velned)/sizeof(*gps_nav_velned));
    unsigned char from_gps_data_nav[gps_nav_velned_length];

    return SPIdev::transfer(spi_device_name.c_str(), gps_nav_velned, from_gps_data_nav, gps_nav_velned_length, 5000000);
}
