Creating Schedule Override Gaps for Holidays

On Creating Schedule Gaps, it goes through purposely creating gaps in schedule coverage where no one is on call. We use this feature for our services that only require business-hours support. I.E. Our desire is that incidents are only created during business hours.

Where this falls short though is holidays. We’d like to setup our schedule so that a gap exists on holidays. That way incidents are not created on holidays.

Is there currently any way to do this? An idea we had was to schedule an Override for our company’s holidays where the override is not assigned to anyone and therefore it creates a gap in the schedule for that time period. But unfortunately it looks like overrides require a user to be assigned to the override.
