XAML

Set FlowDirection as RightToLeft to Accordion.

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:syncfusion="clr-namespace:Syncfusion.XForms.Accordion;assembly=Syncfusion.Expander.XForms"
             x:Class="AccordionXamarin.MainPage" Padding="{OnPlatform iOS='0,40,0,0'}">
 
    <ContentPage.Content>
        <syncfusion:SfAccordion x:Name="Accordion" ExpandMode="SingleOrNone" Margin="5" BindableLayout.ItemsSource="{Binding Info}" FlowDirection="{OnPlatform Android='RightToLeft', iOS='RightToLeft'}">
            <BindableLayout.ItemTemplate>
                <DataTemplate>
                    <syncfusion:AccordionItem x:Name="AccordionItem">
                        <syncfusion:AccordionItem.Header>
                            <Grid HeightRequest="50">
                                <Label Text="{Binding Name}" VerticalOptions="Center" HorizontalOptions="StartAndExpand"/>
                            </Grid>
                        </syncfusion:AccordionItem.Header>
                        <syncfusion:AccordionItem.Content>
                            <Grid Padding="5" BackgroundColor="NavajoWhite">
                                <Label Text="{Binding Description}" VerticalOptions="Center" HorizontalOptions="StartAndExpand"/>
                            </Grid>
                        </syncfusion:AccordionItem.Content>
                    </syncfusion:AccordionItem>
                </DataTemplate>
            </BindableLayout.ItemTemplate>
        </syncfusion:SfAccordion>
    </ContentPage.Content>
 
</ContentPage>

In UWP platform, the ScrollView is not changed when RTL is enabled (framework issue). To overcome this issue, set the FlowDirection property in constructor of MainPage in UWP renderer.

C#

Set FlowDirection to RightToLeft in constructor of MainPage

namespace AccordionXamarin.UWP
{
    public sealed partial class MainPage
    {
        public MainPage()
        {
            this.InitializeComponent();
            SfAccordionRenderer.Init();
            this.FlowDirection = FlowDirection.RightToLeft;
            LoadApplication(new AccordionXamarin.App());
        }
    }
}

Output
