How to decrease logging level reported in Console?
No, reducing verboseness of the macOS logs is not a standard option.

While there may be a Terminal command/flag or a mod GUI app that lets you change the error levels recorded, I'd advise against doing so because if and when you need support/help, the console logs will be one of the places a tech person would review, and if they're truncated then there's less clues for the person investigating an issue.
