Datepicker options (I want to see only exist days on datepicker)

Hi,

i have livestream dashboard. And i have some problem. On my singledatepicker i can select everyday between my start and end date. But only same days I have observations on my dataset.

So when I select a date that doest include any observations, I take some error.And I wanna set singledatepicker to select only exist days. How can I do this?

                        dcc.DatePickerSingle(id='s_day1',
                                        min_date_allowed=df["TimeStamp"].min().date(),
                                        max_date_allowed=df["TimeStamp"].max().date(),
                                        initial_visible_month=datetime.datetime.today(),
                                        date=(datetime.datetime.today()).date()
                                            )

My code same as this one. Can you give me some advice?
