Remote Update Manager (RUM) Executed as local system account AUSST

Can Remote Update Manager (RUM) be executed as local system account and connect to on premise AUSST?

I have set up AUSST on a server, Domain users are abled to connect and update adobe products from the server. I want to be able to use sccm to trigger the updates, but SCCM client runs as the local system account. When I need the local system account to have access to network resources we add Authenticated users to the Appropriate ACL and things work. 

I have tried adding the accounts below to IIS as well as the folder structure and share starting with Read, modify and full rights.

• Authenticated Users
• Everyone
• Domain computers
• Domain users
• As well as the specific AD computer account I am testing on.

Is it possible to run RemoteUpdateManager.exe as the local system account, or execute it as someone other than a domain user. 

Kindly Mark,
