Configure Local Policies:Security Options:Network security on Windows Home (7 or later)

I need to configure a Windows 7 Home machine to connect to a VPN Server. This requires the following configuration:

• Local Policies > Security Options
  
  
  
  • Network Security: Minimum session security for NTLM SSP based (including secure RPC) clients
    
    
    
    • disable "Require 128-bit encryption"
    
    
  
  

In Windows Pro and higher this can be done using secpol.msc, which is not available on Windows 7 Home.

Is there a way to configure this in Windows 7 Home?

A number of suggested solutions are for installing gpedit.msc (Group Policy Editor), which appears to be a super-set of secpol.msc (Security Policy). These, as well as @Maob's pointed Reddit page offer solutions that involves installing software of unknown origin - that's a risk I can't take on a machine meant to securely (over VPN) access protected content.

I am looking to achieve the above with 'trusted' means, so ideally without installing anything new, or using something provided by Microsoft. I am looking to set the above by editing registry, or running some (PowerShell ?) script I can inspect.
