Exchange Server 2016 CU20

Good morning,

Currently, we are on Exchange 2016 CU 19 with the latest security update installed, I know the security update also came out for CU 20. When upgrading to CU 20 do I then need to install that CU update and then the security patch from April(KB5001779) even though I installed them on the server under CU19?
