Is there a way to "pass through" certain controller/gamepad controls (specifically, analog controls) to the game unaltered?

Background: I'm trying to create improved controls for NASCAR Racing 2003 Season (aka NR2003) using a PS5 controller on Windows. This game has native controller support, but only a small number of controls can be customized in-game (namely steering, throttle, brake, clutch, look left/right, and gear shifting). Many other essential controls, including pit crew instructions and pit strategy choices, are hard-coded to the keyboard and cannot be remapped or reassigned in-game, which makes it awkward and dangerous to attempt to change pit strategy on the fly, and nearly impossible when pitting under green-flag conditions.

My goal is to use this or a similar program to map unused buttons on my controller to the hard-coded keyboard controls in question to enable easier pit strategy changes, while retaining the use of analog controls for steering, throttle, brake, and clutch. The game does not support mouse input for these, so in order to have proper analog controls (which is critical for those four functions), I need to pass the analog controls on the controller through unaltered, or otherwise map them to another analog control that the game will recognize (it only accepts keyboard and controller/steering wheel/pedals input).

Is there a way to do this within AntiMicroX? If not, is there another program that will? I have tried JoyToKey, which does pass controller input through if not assigned to a key, but it does not provide me with enough flexibility -- the setup I have created uses one controller button to cycle through F1 -> F2 -> F3 -> etc. -> F8 -> F9 -> back to F1, as each function key from F1 to F9 brings up a different strategy window while driving. AntiMicroX supports cycling between nine (or more) keys, but JoyToKey is limited to cycling through a maximum of four, which is not sufficient for my needs.
