Google Calendar Schedule

I carefully read and watched the post but this is specifically adding reservation to one customer.

Sorry for the misunderstanding, I am looking to set up the schedule on the google calendar. For instance, on my google calendar is there a way where I can manually input work hours for each day which then gets synced to the website?
So when the customer books an appointment the only times shown is the one I set within my calendar for that day.
From this post you’ve provided me I see that you can reserve an appointment to a specific customer when gets synced to the website but is it possible to schedule work hours within google calendar?

Thanks
