Drawing static full screen images using DirectX11

My question is as follows. In most tutorials that I've seen there is a setup part of DirectX11 where you do something like this:

// Set the refresh rate of the back buffer.
if(m_vsync_enabled)
{
    swapChainDesc.BufferDesc.RefreshRate.Numerator = numerator;
    swapChainDesc.BufferDesc.RefreshRate.Denominator = denominator;
}
else
{
    swapChainDesc.BufferDesc.RefreshRate.Numerator = 0;
    swapChainDesc.BufferDesc.RefreshRate.Denominator = 1;
}

Which either sets the refresh to be as fast as possible or synched with the monitor.

However in the application that I need I only want to refresh the screen when I tell the system to do it. Is there any way to do this?

These numbers have nothing to do with the actual refreshing, which happens when you invoke Present. You can call it once per second and screen will be refreshed just once.
