How to set the mouse to not wake up PC in C#?

I made an exe file that puts the screens on standby for when I want darkness in the room to sleep but not to have to put the PC to sleep or hibernate it as this sometimes ruins my Winstep Nexus Ultimate bars and moves them to different screens and the individual windows open and it takes a long time to wake up from hibernation, but when the mouse moves the movement wakes them up, I want to force Windows to not wake up when the mouse moves as this could happen accidentally, I want to use some C# lines of code that running them would make Windows not wake up when the mouse moves (maybe also prevent the keyboard from waking up the standby mode of the screens).

What I have tried:

static void Main()
       {
           System.Threading.Thread.Sleep(2000);
           SendMessage((new Form()).Handle, WM_SYSCOMMAND, (IntPtr)SC_MONITORPOWER, (IntPtr)2);
       }


       static private int SC_MONITORPOWER = 0xF170;
       static private uint WM_SYSCOMMAND = 0x0112;

       [DllImport("user32.dll")]
       static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);
