How does terms affect SEO

How does terms like Kubernetes in a blog article affect SEO?

I noticed that if this term is in plain text in a blog post it decreases readability as Yoast sees it. Though it counts as Focus keyphrase.

So i decided to mark the term as code. It didn’t count as Focus keyphrase, but increased readability.

Now, i’m not sure if this term is considered by search engines or not.

I see blog posts where terms are not marked as code (e.g. Kubernetes)

https://kubernetes.io/blog/2021/12/22/kubernetes-in-kubernetes-and-pxe-bootable-server-farm/

and where they are (e.g. Pod )

https://kubernetes.io/docs/concepts/workloads/

My goal is that these terms will be considered by search engines.
