Add this style in your DataGrid Resources and the selection border will be gone -

<DataGrid>

  <DataGrid.Resources>
    <Style TargetType="DataGridCell">
      <Setter Property="BorderThickness" Value="0"/>
      <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
    </Style>
  </DataGrid.Resources>
