To be honest you lost me with the above, not enough details about what it is you are actually doing/trying. That being said:
Assuming you are talking about the Auto-Matched Tone Curve that is found in the Exposure Tab → Exposure: This one cannot be activated or deactivated in a stored profile. This one only works on-the-fly (as in: press it manually to make RT calculate values for that specific RAW), as mentioned before: The calculated numbers for that specific RAW are stored in a saved profile and not the calculate values action itself (no intelligence).
Besides all that, there’s the issue of applying the Film Negative profile, which already sets some values/curves in the Exposure Tab → Exposure. This profile also uses the default values for the Colour Tab → Film Negative settings. This might be worth looking into and correcting if you are using the same film brand/type negative.
If you apply another dynamic rule that also targets Exposure Tab → Exposure all (!!) previously set settings will be changed/overwritten in this module. Not sure if that is what you want. The film negative profile sets these for a reason, although you might want to change those, that’s up to you of course.
Not sure if you are aware of this but you mention picking the correct camera, lens and DCP profile: You do realize that you need to pick the camera/lens/profile for the camera that “scanned” the negative and not the (35mm film) camera that was used to take the actual image, right? You need to correct the scanning process, the correcting of the film/negative is done via the Film Negative module.
You can automate this, the correcting of the scan, though: Use Auto matched camera profile in the the Colour Tab → Colour Management module. If RT cannot find one it will fall back onto the Camera Standard type. Things become a bit more complicated if you have and are using the adobe DCP profiles extracted from Adobe DNG converter. But if the camera(s) used for scanning are known you can create specific dynamic rules for those.
Anyway, hope you get something out of the above answer(s). If not: Ask again
