Hi @rockand.roll !
It’s not possible to close a developer account without submit a support case. According to the Developers website:

Close an account
DocuSign Support can close a developer account that is no longer in use. This prevents anyone from logging into the DocuSign web app with that account or using it to send API requests. DocuSign cannot reopen a closed account, but you can create a new account if needed.

To request closure of an account, please open a support case with DocuSign Support, opens in new window. If you don't have a production account, select DocuSign API Integration Support under More Support Options, and submit details using the form.
