HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\DefaultMediaCost
(example at https://4sysops.com/archives/set-windows-10-ethernet-connection-to-metered-with-powershell/ )
But since each Ethernet Metered Connection have it own information (since Windows 10 version 1709 I believe, in Settings / Network & Internet / Ethernet / then select your connection), there is a NEW key to know
Where is Network Card connection metered information:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DusmSvc\Profiles\{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}\* in REG_DWORD name UserCost indicate if metered or not
with {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX} your Network Card GUID
and
UserCost = 0 when Metered is off
UserCost = 2 when Metered is on
Below when metered is On
You need to restart "Data Usage" Service DusmSvc before your settings take effect
In registry Network Card ID {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}is in:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards\Y\{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}
With Y= a number
In Powershell to have GUID Network Card
Get-NetAdapter | select InterfaceDescription, InterfaceGuid
or in old Powershell version
Get-WmiObject Win32_NetworkAdapterConfiguration -filter 'IPEnabled=True' | %{$_.GetRelated('Win32_NetworkAdapter')}| select Description,GUID
Using this Script SetMeteredEthernetConnection.ps1 you can do it by yourself
PS C:\temp>
.\SetMeteredEthernetConnection.ps1 -MeteredAction DisplayNetworkCardOnly
Display Network Card: 'Intel(R) 82579LM Gigabit Network Connection' ID:'{2FD6004A-2CB4-4B1E-ACEB-CC5792236B44}'
PS C:\temp> .\SetMeteredEthernetConnection.ps1 -MeteredAction DisplayNetworkCardOnly -NetWorkCardLike giga
Display Network Card: 'Intel(R) 82579LM Gigabit Network Connection' ID:'{2FD6004A-2CB4-4B1E-ACEB-CC5792236B44}'
PS C:\temp> .\SetMeteredEthernetConnection.ps1 -MeteredAction DisplayNetworkCardOnly -NetWorkCardLike NOOO
PS C:\temp> .\SetMeteredEthernetConnection.ps1 -MeteredAction MeteredOff
Set MeteredOff to connection Intel(R) 82579LM Gigabit Network Connection
