You can edit Group Policy in the Command Prompt using the Group Policy Management Console (GPMC). To do this, open the GPMC and select the Group Policy object (GPO) you want to edit. Right-click the GPO and select Edit. This will open the Group Policy Editor.
In the Group Policy Editor, go to Computer Configuration > Administrative Templates. Under Administrative Templates, you'll see a list of policy settings. Double-click on the policy setting you want to edit.
In the policy setting window, you can enable or disable the policy setting, and configure it as required. Once you're done, click OK.
