What subfields in computer sciences may one study without learning Object Oriented Programming?


What subfields in computer sciences may one study without learning Object Oriented Programming or is there some kind of degree in Computer Science without the OOP knowledge requirement?

Is there a language without OOP?

Does one need to know OOP to simulate a CPU?

I wanted to earn a CS degree without ever learning OOP. Is there a name for that?

My guess what that Computer science without OOP is simply applied Statistics or Machine Learning using SKlearn and packages.
