I'm not sure I understand what you need, but:
1.Have you tried to open the notification panel, then select (hold) the mobile data icon(or another icon) for a few seconds? That should open the menu for that specific icon(function). OR
2. Just tap on Mobile data icon in notification panel, and that should enable/disable the function.
I hope this helps.
See below some print screens with what I have available in my notification panel. For you it's different? Be aware that there are two pages with icons.
can you please go to dial screen and input *#1234#, make a print screen and share it here?
Thank you. I'm having a look and will revert when I have an update.
