I have a keybind (TAB) set to hide the MiniHUD rendering when held. This way when I want to view the tab list the info toggles won't cover it up.
However, whenever I press down or let go of the key, it brings up an action bar message saying that the rendering has either been enabled or disabled.
It doesn't break anything, but it's just super annoying (especially when another action bar is being shown).

This is possible in the rewritten malilib code that is being worked on in 1.12.2. Every hotkey has an option to choose where (or if) the possible toggle message will show up. And there is also a separate message redirect system that works based on the message localization key, which likewise also allows you to redirect the message to any of the supported message renderers, or to disable it.

No idea of an ETA to anything like 1.17+ yet though. But new 1.12.2 builds should start relatively soon.
