To implement metered connection detection, set cost level to 0x02 or 0x03 as described in Microsoft Windows article. NM 1.31.5 and before has a bug in MS-NCT implementation because second Reserved byte is used instead of Cost_Level byte. According to NM code, value of this byte must be greater than 0x01 to make NM think connection is metered. According to [MS-NCT], the byte used by NM SHOULD always be 0x00, so it may cause compatibility errors, so you can change it on your own risk.
