Is there any way to only turn off the monitor without locking the computer?

Sure. You could use this below instead for that. :)

You can turn off the monitor the workstation without a 3rd party program with a PowerShell-script: Make a MonitorOff.ps1 for example in C:\ and create a shortcut with this target: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy UnRestricted -File C:\MonitorOff.ps1

Paste the following code inside the .ps1 file:

Code:

# Turn display off by calling WindowsAPI.
 
# SendMessage(HWND_BROADCAST,WM_SYSCOMMAND, SC_MONITORPOWER, POWER_OFF)
# HWND_BROADCAST    0xffff
# WM_SYSCOMMAND    0x0112
# SC_MONITORPOWER    0xf170
# POWER_OFF          0x0002

using System;
using System.Runtime.InteropServices;
 
namespace Utilities {
    public static class Display
    {
        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        private static extern IntPtr SendMessage(
            IntPtr hWnd,
            UInt32 Msg,
            IntPtr wParam,
            IntPtr lParam
        );
 
        public static void PowerOff ()
        {
            SendMessage(
                (IntPtr)0xffff, // HWND_BROADCAST
                0x0112,            // WM_SYSCOMMAND
                (IntPtr)0xf170, // SC_MONITORPOWER
                (IntPtr)0x0002  // POWER_OFF
            );
        }
    }
}
