For the curious, there’s an option in Home Assistant’s CLI that allows you to disable the “content-trust” feature (i.e. it will cease checking for source-code modifications).
ha supervisor options --content-trust=false
If you do this your instance of Home Assistant will be flagged as “unsupported”. However, it will allow for source-code mods, such as adjusting the frequency of connectivity/version checks. Optimally, the frequency could be configured and so there would be no need to patch the code.
