Supress output of chromedriver

Question

According to the answers in the question "Suppress console output in PowerShell" and several other ressources, I should be able to suppress all output by redirecting all ouputs to null on chromedriver.

Powershell, variant 1:

./node_modules/chromedriver/lib/chromedriver/chromedriver.exe --port=8015  *> $null

Powershell, variant 2:

./node_modules/chromedriver/lib/chromedriver/chromedriver.exe --port=8015  | Out-Null

Powershell, variant 3:

[void] (./node_modules/chromedriver/lib/chromedriver/chromedriver.exe --port=8015)

Also on node I do fail to supress output:

var cp = require("child_process");
chromeDriverProcess = await cp.spawn(
    __dirname + '/node_modules/chromedriver/lib/chromedriver/chromedriver.exe',
    ["--port=8015"],
    {
        stdio:'ignore'
    }
);

I still get messages like: DevTools listening on ws://127.0.0.1:58230/devtools/browser/18d5a160-cd43-488b-b969-cf91caf3f8df

Using the switch --silent on chromedriver and --log-level=3 on chrome does supress some of the outputs, but not the one mentioned above.

How does chromedriver output its data? How do I supress all output done by chormedriver?
