是的，您可以使用Entry来实现这一点，并为其设置IsEnabled。对于您的布局，建议您使用Grid来实现这一点。
请参考以下代码：

<StackLayout Orientation="Vertical"> 

    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="60"  />
            <RowDefinition Height="60" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="100" />
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>

        <Label  Text="Address:"  Grid.Column="0" Grid.Row="0" VerticalOptions="Center"  />

        <Entry x:Name ="patientAddress"  Text="address 1" Grid.Column="1" Grid.Row="0" BackgroundColor="Yellow"   IsEnabled="false" />

        <Label  Text="Phone:" Grid.Row="1" Grid.Column="0" VerticalOptions="Center" />

        <Entry x:Name ="patientPhone" Text="address 2"  Grid.Row="1" Grid.Column="1"    BackgroundColor="Yellow"  IsEnabled="false" />
    </Grid>

    <Button Text="Edit" Clicked="Button_Clicked"/>

</StackLayout>
