Is mapping controller buttons to single keyboard keys allowed?

I use a custom DualShock 4 controller in Apex Legends.

I have the following 1:1 mappings:

• Touchpad → keyboard Z key
• PS button → keyboard T key

Each physical controller button outputs only one keyboard key.
There are no macros, turbo functions, rapid fire, multiple inputs, or automated actions.

Is this type of mapping allowed under the current Apex Legends anti-cheat rules?

I am specifically asking whether assigning a single keyboard key to a controller button is allowed, as long as it remains strictly one button press = one key press.
