Oracle oledb does not support sysdba login by sys

Common connection strings of Oracle oledb are as follows:
"Provider = oraoledb. Oracle; Data Source = myoracledb; user id = username; Password = asdasd ;"
Here, the user ID can be written to system and can be successfully logged on. However, if it is written as sys, there will be an error message: SYS must be logged in as sysdba. However, Oracle oledb does not support the following methods:
User ID = sys as sysdba;
The reason is that the ole db standard does not support this method.

If you want sys to Log On As sysdba, you can only use ODBC.

The related information is as follows (I have tried Oracle 10g, but it still does not work ):
