[Feature Request] Registry Tweak to prevent Chrome from downloading potentially unwanted 4gb LLM models

[mgrimace]

Hello, for reference Google Chrome is now silently downloading a 4gb LLM model locally, this adds up fast on our family computer with multiple users (source: https://pureinfotech.com/stop-chrome-gemini-nano-download-windows-11/, https://www.theregister.com/ai-and-ml/2026/05/07/chrome-silently-installs-a-4-gb-local-llm-on-your-computer/5230893, etc).

The registry tweak to block the download at a policy level appears to be to create a new DWORD32 value at:

• HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome
• GenAILocalFoundationalModelSetting, set to value 1.

There are also flags that can be set in each chrome instance, but this blocks it at the computer level AFAIK. Thank you!
