Windows service PSSession (WINRM)

I’m running Gitlab runner on a Windows server 2019 with a local system account.
We use PSSessions in our gitlab-ci file for uploading files to another server.
Currently only Administrators are able to use PSSessions (WinRM).
Can we configure Powershell or WINRM to allow local system account as well?
I don’t want to give the gitlab-runner service full admin rights and search for another solution.

Can anyone help me with this?

Thank you!

Local System is restricted to not allow outbound network connections. This is a windows security feature. Change the service to run as Network Services. If prompted for password enter blank password. New-PSSession etc will run at that point.
