Aras 12.0 SP9 VaultServer config

how to config file url token in 12.0 SP9?

In the  previous version we can config like this:

<enforce_user_credentials>0</enforce_user_credentials>

But there is no such file  "VaultServerConfig.xml" at 12.0 SP9.

I only found the file "vault.config" ,but don't know the key  name in the appsetting.
