How to add new beans programatically on startup without an extension?

[HerrDerb]

I would like to add N beans on startup depending on collection entries (HealthChecks)
I tried to do this with @Observes AfterBeanDiscovery event, which did not get triggered. I figured that this is not supported in Quarkus as CDI Lite implementations are not required to provide support for Portable Extensions.

How can I add additional beans during runtime within an application code (no extension)?

As it was an issue with health checks, I was able to solve this by register them manually with the help of HealthRegistry and HealthRegistries
