Running a powershell script saved in another server

Hi.

I am having trouble running a powershell script saved in another server.
I need to execute the powershell script by C#.
Server 1 is where the C# program is saved
Server 2 is where the powershell script is saved.

Here is my c# method

where variable serviceList is the parameter/argument to be passed to the powershell script.

variable psPath will contain the string like "\\[serveripaddress]\g$\adminscripts\dotalltool_scripts\stopservice.ps1

public string runScriptPS(string serviceList, string operation)
        {
            string psFileName = operation == "Stop" ? "stopservice.ps1" : operation == "Start" ? "startservice.ps1" : "restartservice.ps1";
            string server = hdnServerSelected.Value;
            string psPath = @"\\" + server + @"\g$\AdminScripts\dotalltool_scripts\" + psFileName;
            string paramSapArray = (char)34 + serviceList + (char)34;
         


            Runspace runspace = RunspaceFactory.CreateRunspace();
            runspace.Open();

            RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
            Pipeline pipeline = runspace.CreatePipeline();
            Command psCmd = new Command(psPath);
            CommandParameter sapParam = new CommandParameter("SAPArray", paramSapArray);
            psCmd.Parameters.Add(sapParam);
            pipeline.Commands.Add(psCmd);

            Collection<PSObject> results = pipeline.Invoke("Set-ExecutionPolicy Unrestricted");

            

            StringBuilder sb = new StringBuilder();
            foreach (PSObject obj in results)
            {
                sb.AppendLine(obj.ToString());
            }
            string a = sb.ToString();
            return sb.ToString();
        }

Here is the error that I am getting

File \\serveripaddress\g$\AdminScripts\dotalltool_scripts\stopservice.ps1 cannot be loaded. The file \\serveripaddress\g$\AdminScripts\dotalltool_scripts\stopservice.ps1 is not digitally signed. You cannot run this script on the current system.

What I have tried:

I already indicated execution policy on the pipeline.Invoke()
