What are the usage limits of controller mapping under the new anti-cheat rules?

Hello anti-cheat team, I’m glad to know that you have finally taken action against converter cheating. However, it also raises concerns for our controller player community: how can we use controllers without getting banned? 

I am a controller player with 1000 hours of controller player. During constant practice, I discovered my own limitations, so I chose a Chinese controller with extra buttons. It can map the controller's own buttons via its built-in driver and also map keyboard keys, giving me greater competitive advantage. 

For example: I use the extra buttons to map the R key on the keyboard, which allows me to reload while blocking a door without opening it. I can map the T key so that in the game I don't have to reach for the keyboard or set the microphone to stay on.

I want to ask you: if the built-in buttons or extra buttons on the controller are mapped to keyboard inputs, will this cause a ban?

Looking forward to your reply, thank you.😁
