If FRS/BRS being used to pay as Premium of CPF Life at age of 55 or 65, and a PR renounce his PR at age 58, does he get back full amount from RA without paying the CPF Life Premium?

This is a question with regards to CPF and PR status. Some PR holder plan to leave Singapore and renounce his PR beyond the age of 55, let said 58, does him able to withdraw all his money from retirement account without participate in CPF LIfe ? Or the Full Retirement Sum already used to pay to the CPF Premium at the age of 55, or locked in, and there is no way to withdraw the locked in Sum. Need clarification. Thanks.
