This command will suspend the ACME account, preventing it from being used to request certificates without fully deactivating the account.
Using the instant=1 parameter permanently and immediately deactivates the ACME account, with no option to restore it. This action is useful when you want to prevent ACME accounts from ever being used to request certificates again. However, as domains can only be removed from active accounts, any domains left behind at the time of deletion will not be eligible for a refund, even if within the 30-day window.
