Hello.
1) Please note, if you will activate this option “Allow unlimited bookings per same day(s)” at the Booking > Settings General page in Advanced section, so days in calendar, will be available in any case, do not depend if you continue import of events from other sources or not.
2) In case, if you want to stop import new bookings from other sources, so then just remove the booking import shortcodes, like this
[booking-manager-import url='https://calendar.google.com/calendar/ical/CALENDAR_ID/public/basic.ics' resource_id=1419 import_conditions='if_dates_free' from='today' from_offset='1d' until='year-end' until_offset='2h' max=500]
from the page(s).
3) Relative export of bookings from the Booking Calendar to other sources, you can change the URL of exist .ics feed at the Booking > Settings > Sync > “Export – .ics” page. Or you can check in some other source (like airbnb or booking.com), in settings, how to stop import such .ics feeds anymore. Please check it with support of specific service.
Please check more about import / export of .ics feeds here: https://wpbookingcalendar.com/faq/#sync
Kind Regards.
