Does ISP have this crazy feature?

Hello,
Background:
I have a camera module, based on IMX378, where the lens was replaced with a different one, and as was later found out - an incompatible one. I have to say that it is very improbable that there are exist compatible lenses that meet our requirements (parfocal ~5-100mm).
After Lens Shading Correction was calculated and applied it became obvious that there is a severe desaturation around the edges of the frame. This is likely caused by a mismatch in ray divergence angle and the sensor is likely built to accommodate that specific angle.
The application that uses this sensor is a simple GStreamer pipeline run via gst-launch1.0 (because I have no experience in writing such applications in C++, and also I have no experience in Cuda. Both of those things are not very straightforward for me even if you give me the code to run/compile)

The question itself: is there any way to utilize the ISP of the Jetson Nano to correct that defect (apply vibrancy so that it is compensated) in real-time (we’re talking 1080p@120 stream).

Or maybe someone knows (very unlikely) where I can get a pair of IMX378s in BGA packages with at least a pinout (I have a partial datasheet that is enough to run those) so I can make a replacement?

Thank you. Anything will be appreciated.

Sorry, for this cause need tuning process and only scaling partner can access those tuning tools.

Do you mean those tuning tools?
Who I need to call so the tuning could be done?

Yes, and check below link for partner.
