Solutions I’ve found for this:
1. Disabling a concrete extension update
That’s what I wanted!
You can do this by editing the extension’s manifest.json file:
-
On Windows:
C:\Users\<USERNAME>\AppData\Local\Google\Chrome\User Data\Default\Extensions\<EXTENSION-ID>\<VERSION>\manifest.json(find out the extension’s ID by enabling Developer Mode in the extension settings page) -
On MacOS: Open
/Users/USERNAME/Library/Application Support/Google/Chrome/Default/Extensions/EXTENSION-ID/VERSION/manifest.jsonin a text editor. -
On Ubuntu for Chromium:
${HOME}/.config/chromium/Default/Preferences
In this file, set the "update_url" property to something invalid like "https://localhost" for example. For the given url, it makes auto-updating that extension as simply impossible.

2. Disabling all Google Chrome extension updates
