STEP 1: Set InlineViewMode as Agenda, and set ShowInlineEvents to true for displaying events.

<calendar:SfCalendar x:Name="calendar"
                             ShowInlineEvents="True"
                             InlineViewMode="Agenda"
                             DataSource="{Binding Appointments}">
        <calendar:SfCalendar.BindingContext>
            <local:ViewModel/>
        </calendar:SfCalendar.BindingContext>
</calendar:SfCalendar>

STEP 2: By using the MonthChanged event in the calendar, you can call the ClearSelection method to clear selected date and its appointments in the AgendaView.

private void Calendar_MonthChanged(object sender, MonthChangedEventArgs e)
{
            this.calendar.ClearSelection();
}
