How can you enable/disable a chrome or edge browser flag with WebView2?

[tamuseanmiller]

I'm trying to find a way to specifically disable a browser flag like the ones in chrome://flags or edge://flags on my local device to test inside of WebView2. Can I use something like WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS to do this and if so how can I use it?

I was trying to use this to disable a flag like this:

WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS="enable-tls13-kyber=false"

Any ideas?
