You can prevent guests from booking on specific days of the week across your calendar. There are multiple ways to do this:
Easiest Way
Go to Calendar
Availability
More Availability Settings
Restrict Check-in Check-out Days
More Complicated & Alot More Work
Turn on Pro Tools and create a Rule Set to restrict check-in & check-out dates and apply individually to dates you want on your calendar (this will override any default settings you have on your regular calendar.)
The system does not "prompt" you to make any changes to your settings. That is up to the Host.
