Hello QuizzBox,

Thank you for writing.

You can handle the CellFormatting event of the grid and modify the HotTracking element state. Please note that if you need to apply the custom styles based on some conditions you will also need to reset them because of the virtualization: 

private void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
{
    if (!e.Row.IsSelected && e.Row is GridViewDataRowInfo)
    {
        e.CellElement.SetThemeValueOverride(LightVisualElement.BackColorProperty, Color.LightGreen, "GridDataCellElement.HotTracking");
        e.CellElement.SetThemeValueOverride(LightVisualElement.BackColorProperty, Color.LightGreen, "GridDateTimeCellElement.HotTracking");
        e.CellElement.SetThemeValueOverride(LightVisualElement.BackColorProperty, Color.LightGreen, "GridCheckBoxCellElement.HotTracking");
    }
    else
    {
        e.CellElement.ResetThemeValueOverride(LightVisualElement.BackColorProperty, "GridDataCellElement.HotTracking");
        e.CellElement.ResetThemeValueOverride(LightVisualElement.BackColorProperty, "GridDateTimeCellElement.HotTracking");
        e.CellElement.ResetThemeValueOverride(LightVisualElement.BackColorProperty, "GridCheckBoxCellElement.HotTracking");
    }
}

I hope this helps. Should you have further questions please do not hesitate to write back.
