Only clickable timeslots visible?

Hello team,

My previous questions are answered. Thank you for that.
I have one more question at this moment.
Is it possible to show only the timeslots that are ‘open’ for booking?
The working day is 08:00 until 17:00. The timeslots are 10 minutes.
A service provider has timeslots on Monday from 10:00 to 11:50.
On Wednesday he has timeslots from 14:00 until 15:20.
I prefer not to see the timeslots that can’t be clicked.
E.g. Monday 08:00-09:50 and 12:00-17:00 and Wednesday 08:00-13:50 and 15:30-17:00

Thanks for your help.
Albert
