I wouldn't consider CyberCapture "Essential" but it is an important part of zero-day detection. But I mean if you turned it off, behavior shield would still probably detect anything malicious.
That being said, if you are a developer you'd be better off using Avast Free, for some reason Avast decided to absolutely butcher any and all customizability in Avast One.
Anyways, if you are using Avast One, it does have an option for CyberCapture, it's located under "File Shield" and "Advanced Settings", just uncheck the box in the image below that says "Analyze unrecognized files", I'm not sure why the setting doesn't mention "CyberCapture" in the title or description, seems like a UI oversight, but I have confirmed through testing that it is the toggle for CyberCapture.
My biggest gripe with Avast One is how they've consolidated File Shield and Behavior Shield into one.
