Microsoft Form Customize Calendar

I am creating a form in Microsoft form that feeds into a SharePoint list that users can submit questions/queries.

One of the questions is What is your deadline for this question? They will select a date from a calendar.

I want to blackout the next three dates after the form creation date. For example, if a user creates a form on 15 Nov 2020, the next available date they can select for a deadline is 19 Nov 2020.
