Hopefully this helps and gets you whatever functionality you were trying to find. So I now have the behavior I seek where the key is usable for a specific task, but not in a way that my game/browswer/software normally interpret as a keybind that is typically used. Now when setting up my voice comm push-to-talk, rebinding them now associates it with a typically unused input, and ends up being configured as 'Unknown' (Mumble), 'UNK135' (Discord), or '135' (TeamSpeak). So now, instead of sending a 'Back' command, I'm now sending a F24 keystroke. For my configuration, however, I don't have any obvious functionality assigned to F23 and F24 despite having some functionality with fn-F12 that turns off my keyboard backlighting. Most computers/keyboards only have F1-F12 keys, with perhaps a function key to get another 12 keybinds. Logitech G Hub apparently recongizes F keys, at least on my laptop, up to F24. When you plug it back in go the Logitech website and reinstall the G hub. Right click USB Composite Device and Uninstall unplug your mouse or Logitech devices. drop down menu for your device will show when you click on it. So, if I was alt-tabbed to a web page while talking, I'm suddenly looking at a very different page, like perhaps my home page. Open Device Manager press VIEW, devices by container. This led to instances where I'd press back to talk, and then whatever window I had active would receive a back command and execute it as applicable. So, the specific problem I was trying to solve was that I use the back and forward buttons on the side of my mouse for push-to-talk keybinds on my various voice communication software while gaming.
