Hello and good day Rafał J. Thank you for the inquiry. I will be posting a DJI link where you can unlock a NFZ https://www.dji.com/flysafe/self-unlock. Thank you.

You will need to use the custom unlocking on the flysafe page. You will also need to upload a copy of the written authorization. Then DJI will determine if the zone will be unlocked or not.
Good Luck.

thank you for reply
