I want to set the background mode of all windows to Gradient2Color. I searched the forum resources and found no information. Please help me.

As far as I know, background styles are not related to viewports but they are related to displayModes.
But in your case, you can change the background style in displayMode of all your viewports.

import Rhino
for view in Rhino.RhinoDoc.ActiveDoc.Views:
    displayMode = view.ActiveViewport.DisplayMode
    displayMode.DisplayAttributes.FillMode = Rhino.Display.DisplayPipelineAttributes.FrameBufferFillMode.Gradient2Color
    Rhino.Display.DisplayModeDescription.UpdateDisplayMode(displayMode)

You can use DisplayPipelineAttributes.SetFill method:

import Rhino
import System
for view in Rhino.RhinoDoc.ActiveDoc.Views:
    displayMode = view.ActiveViewport.DisplayMode
    displayMode.DisplayAttributes.FillMode = Rhino.Display.DisplayPipelineAttributes.FrameBufferFillMode.Gradient2Color
    displayMode.DisplayAttributes.SetFill(System.Drawing.Color.Black, System.Drawing.Color.White)
    Rhino.Display.DisplayModeDescription.UpdateDisplayMode(displayMode)
