Silence macOS Storyboard warnings in the debugger console

Question

I'm creating a custom NSToolbar, with custom display and sizing (based on your version of macOS), using Storyboards (I know, I know... sue me, but it needs to be done in Storyboards for reasons important to the client).

However, due to all of these custom properties, my console is now getting overloaded with object-clipping warnings:

I have tried implementing my own macOS-variation of the only consistent StackOverflow solutions that I've found, as well as this gist – still no dice.

UserDefaults.standard.setValue(false, forKey: "_UIConstraintBasedLayoutLogUnsatisfiable")

Is there a macOS solution for Cocoa-based Storyboards that will allow me to silence these warnings?

Furthermore, I tried to find a list of those Apple-included UserDefaults, but have not come across any useful resources. Where are developers finding UserDefault keys such as "_UIConstraintBasedLayoutLogUnsatisfiable"?

EDIT: It would be preferable if there were a solution that silenced, for example, only object-clipping warnings or only warnings for this specific NSToolbar/NSWindow. I do NOT want to silence all Storyboard warnings – as this is a last resort.
