Problem with the format of the row index obtained in the import of quotes.

Dear All. Using "df_closes = googl.history(start= start_date, end=end_date)", the index of the rows has the following format. "DatetimeIndex: 331 entries, 2020-01-06 00:00:00-05:00 to 2021-04-28 00:00:00-04:00". is there a way to get it to have the format "datetime and "YY-MM-DD". Best regards
