You can set this in Delphi, but it needs to be done differently. What your code does is that simply creates and manipulates in-memory data which are not tied to the actual component performing the operations.

This is how to do it:

1. create an instance of EasyUAClientConfiguration.
2. set its .SharedParameters.EngineParameters.CertificateAcceptancePolicy.AcceptAnyCertificate to True.

Please read this:

opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...%20Instance%20Certificate.html

and

opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...ited%20User%20Interaction.html

If you know that you trust the server certificate: You can "accept" it every time. Or, you can move it from the rejected certificates store (typically CommonApplicationData\OPC Foundation\CertificateStores\RejectedCertificates) to the trusted peers store (typically CommonApplicationData\OPC Foundation\CertificateStores\UA Applications).
