We don't recommend this because while we trust ourselves debugging your browser, once you change this setting you will NOT be notified if other extensions are debugging.
So please be aware of this before changing the setting. However, we get that the yellow bar can be totally annoying so here is how to turn it off.
(2) Scroll down or search for "Enable Silent Debugging"
(3) Click ENABLE
(4) Relaunch Chrome
If you change your mind, you can go back to chrome://flags and click DISABLE
