SQL Server update from DDR to CU-17

I am using SQL Server 2017 DDR version 14.0.2002.14. I want to upgrade to the latest possible version of SQL Server 2017. Can I download CU-17 and directly run the latest cumulative update, which is the CU-17 version 14.0.3238.1? OR do I have to reinstall SQL Server 2017 RTM version 14.0.1000.169 first?
