Can I block real IP leak by WebRTC in the browser’s setting?

WebRTC is a web feature which lets you do things like making phone calls or video chats in the browser using direct UDP connections, which is supported by all modern web browsers. However, it could reveal your public and/or private IP addresses to the other party, even if you have the VPN/proxy server turned on to conceal your real IP. You can check here: ip.voidsec.com

To fix this, we can just disable WebRTC on Firefox, or set WebRTC IP Handling Policy to Disable non-proxied UDP on Brave; otherwise, it seems that we have to resort to some external extension such as for this.

As a browser that values privacy and security, would Vivaldi add options for Toggling WebRTC and/or Setting WebRTC IP Handling Policy in Tracking Prevention?
