Turn off (not disable) Action Center icon via registry in Windows 10

Howdy,
We can easily disable Action Center icon in Windows 10 via the following registry key:

Code:

[HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Windows\Explorer]
"DisableNotificationCenter"=dword:00000001

But that will completely disable Action Center and its button will become gray, not possible to change its state.
I don't wanna disable it, just wanna turn it off, like we do manually in:
Settings > System > Notifications & Actions > Turn system icons on or off
For this one, I didn't find a registry key, also the following article does not work for Windows 10:


System Icons - Enable or Disable


Please help me find a way to just turn it off via registry without disabling and locking down the Action Center button.
* Must be via .reg or .bat.

Thanks in advance :)
