Selenium Java - disable WebAuthn functionality in ChromeDriver

Is there a way to disable the WebAuthn-API in the ChromeDriver?

I tried to add an extension, but this did not work.

final ChromeOptions options = new ChromeOptions();
options.addArguments("--load-extension=/path/to/extension");
...

manifest.json:

{
  "name": "Disable WebAuthn",
  "version": "1.0",
  "manifest_version": 3,
  "description": "Disables Web Authentication API for testing purposes.",
  "content_scripts": [
    {
      "matches": ["<all_urls>"],
      "js": ["disable_webauthn.js"],
      "run_at": "document_start"
    }
  ]
}

disable_webauthn.js:

Object.defineProperty(navigator, "credentials", {
  get: () => undefined
});```
