How to disable network adapter in server 2012

I just want to disable network adapter by index 27.
PS C:\Users\ad> Get-NetIPInterface

ifIndex InterfaceAlias                  AddressFamily NlMtu(Bytes) InterfaceMetric Dhcp     ConnectionState PolicyStore
------- --------------                  ------------- ------------ --------------- ----     --------------- -----------
21      vEthernet                                      IPv6                  1500               5 Enabled  Connected         ActiveStore
27      Local Area Connection* 12       IPv6                  1300                5 Enabled  Connected         ActiveStore
1       Loopback Pseudo-Interface 1     IPv6            4294967295       50 Disabled Connected       ActiveStore

In network center there is no such adapter Local Area Connection* 12. Get-Netadapter also do not show this Local Area Connection* 12 also.
Wmic  get name, index shows index  27 with name Hyper-V Virtual Ethernet Adapter #2. SO IT IS ACTUALLY 21 index. I cannot disable it with wmic, because i will lose connectivity
How to disable using Get-NetIPInterface, because it is the only place where it is shown.
Thanks

Hello,

In the operating system do the following.

Execute a run
place ncpa.cpl (to show you the network interfaces)
Select the interface to go to deactivate
Right click and click on disabled.

I remain attentive to your comments.

The particular interface do not appear in there  ncpa.cpl
By the way ipconfig show this adapter as Tunnel adapter local area connection #12
Open device manager, go to view > select show hidden devices expand network adapters > right click on the adapted you want to remove then select uninstall
How to know which adapter is which? ipconfig shows Tunnel adapter Local Area Connection* 12:
Device manager do not show something with tunnel named
Is it safe to disable IP helper service?

ALSO it is none of these:

PS C:\Users\Ad> netsh int teredo set state disabled
Ok.

PS C:\Users\Ad> netsh int 6to4 set state disabled
Ok.

PS C:\Users\Ad> netsh int isatap set state disabled
Ok.


PS C:\Users\Ad> ipconfig

Windows IP Configuration

Hello,

Please share a screen printer of the device manager, showing the network adapters.

I remain attentive to your comments.
