The account provided "TVBYEHMKW5SFQ" is an Indian business sandbox account and direct payment is not available in India, so I can't enable DPRP on this account.
If you want to test the functionality of direct payment and direct payment recurring payments, then you would need to create a sandbox business account in a supported country, such as the United States, then upgrade the account to payments pro. If you want DPRP on the account also, you would need to request that here.
