Is there a function for removing axis bindings that operates like the function for removing action bindings (UInputComponent::RemoveActionBinding)? If not, why not?
Unlike ActionBindings, the AxisBindings array is public. So you can simply access it and remove what you need to remove. Like that:
InputComponent->RemoveActionBinding(0) //Remove Action Binding from index 0
InputComponent->AxisBindings.RemoveAt(0);//Remove Axis Binding from index 0
Hope this helps!
