Booking one day

I need make appoitments for one day. How can I set the booking page to show only one specific date without choosing calendar?
For example:
The appoitment will be 28.3.2024 so there will be for this appoitment only showed this date without option to choose another date.

And is it possible to show on the appoitments page how many places are still available? I choose in setting of the page max. people 50 - attached picture.
And would like to show on the appoitments page rest of the places.
For example:
Already booked 13 people so on the page would be showed "37/50 available" or "still available 37 places" etc.

Thank you.
