Is adding my CA's certificate to "cacert.pem" enough to set it in the TLS configuration?

I saw in the source code of the engine that the SSL manager parses a bunch of certificates from common CAs (SolutionDir/UnrealEngine/Engine/Content/Certificates/ThirdParty/cacert.pem) and I suppose it adds them in the TLS configuration of the HTTP client. I want to also add my own certificate to the TLS configuration so that I can enroll gameplay objects, so I added the certificate my CA emits in that same file, but is that what I have to do? Or do I have to do something else?
