enable filestream in configuration manager

[SQLFanboy]

Hello, I want to enable filestream for a database. But filestream was not necesssary before, so it is not installed on the server. Microsoft tells in the docs to enable it inside the configuration manager first and then enable it to the database with "sp_configure filestream_access_level". DBATool offers for this "Enable-DbaFilestream", which is like the sp_configure order, but I can't find the scripting command for changing the filestream settings inside the configuration manager. Is there a possibility to change this with a script with or without dbatools?
