Does Crash Assistance help with extraction of internal memory?

Crashed Mavic 3 Pro into the lake 200 meters off shore. The drone sank 6 meters deep, retrieved 23 days later. Safely extracted the almost full 256Gb SD card. Bathed the drone in 99% isopropyl alcohol and let it dry for 20 hours. Tried to power up, didn't work. Disassembled the drone on my own, cleaned out maybe 2 times more sand and dirt than after 99% alcohol. Still was not powering up. Maybe a short circuit happened at the time of drowning of the drone. Anyways, I have access to the motherboard and 4 power pins that can be connected to M3 battery through existing frame. Dying to see the crash video and submerging of Mavic 3 Pro to a 6 meter depth but it was recorded on the 8Gb internal memory at the time of the crash. Does DJI Crash Assistance offer the internal memory extraction services?

Not that I have ever heard of. DJI services usually just swap the drone for another and send you on your way.

If the board can't be powered up not much chance, maybe a company that does chip-off data recovery could do something if the flash storage isn't encrypted, but then you have to decide whether the footage is worth a couple thousand bucks or so.

Is this a duplicate of the How to access 8Gb internal memory of M3Pro that doesn't power up after 20 days in a 6 meter deep lake? thread?
