Thank you for your post!
Unfortunately, you can't customize the "delete automatically" date of 30 days. However, if you'd like to be able to customize this period (+/- the current preset date), I'd recommend leveraging our user voice forum to create a feature request for our engineering teams.
As of right now, if you'd like to extend the date of permanent deletion, you can always restore/bulk restore the user(s), and then re-delete them to reset the permanent deletion date for another 30 days.
For more info:
Restore or remove a recently deleted user using Azure Active Directory
If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
