Missing customizable Hotkeys

There seem to be Hotkeys in Battlefield 6, that you aren't able to change.

For example pressing "C" while in class selection/respawn, will move your class selection one to the right.

For me as a player that uses "C" as a Push2Talk hotkey in voice chat. Makes it absolutely anoying as everytime I respawn I spawn as the wrong class, have to suicide and select the old class again.
