I am trying to create a host pool VM using the “Custom configuration” option. The custom solution suggested in the instructions (https://raw.githubusercontent.com/Azure/RDS-Templates/master/wvd-sh/arm-template-customization/script.ps1) does not seem to have done anything. I tried connecting directly to the VM through a bastion using the local admin user/pass, and tried running the solution script manually. There, the error was:

File C:\Userslocaladmin\VD0T\Virtual-Desktop-Optimization-Tool-main\Windows_VDOT.ps1 cannot be
loaded because running scripts is disabled on this system.
For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.

Am I doing something wrong here, or are the instructions incorrect?
