Disable or switch off zigbee on C-7

Hi all,
I'd like to ask if there are any possibilities to disable/switch off zigbee part of the C-7 box.
I do not have any zigbee devices so not necessary to be enabled.
I tried to disable the option "Enable Zigbee Radio" but after the reboot it was enabled again.
Thanks in Advance

Did you click the "Update" button after selecting the Disable Zigbee Radio option?


Thank you very much. Update button did required magic :wink:
I wasn't aware that UPDATE button need to be used as well.
