Yeah immortality in cyberpunk only ever works by being digitalized in the net. With that concept, you can go for different things.
If you want a physical self, you either have special bodies to download into, or take control of someone elses who might be compatible. This could easily be a gameplay mechanic, even. But if it's the endgame goal to get this one, legendary special implant...
Also, if it was an implant that did this - your body gets destroyed, so you lose the implant. At that point, it would be more of a one-time use thing, and there would have to be a whole ton of these implants to keep getting and using them, making them not a prototype kind of thing anymore.
As such, true immortality would absolutely have to be the pure digital side of things. You can't download yourself into something that traps you in mortality again. Copies? Memory sync? Maybe it's urban legends, and the real deal actually results in a horrible state of "shadow of your former self" that you can't escape.
I'm not familiar with the franchise though, so I can only go by Ghost in the Shell, Blade Runner and other reoccurring cyberpunk concepts.
Also, there was a movie about a team of scientists trying to create a digital conciousness of one of their friends with terminal illness, and they managed to do it shortly after he had passed away. He was integrated into a complex where he could control everything, and tons of holographic displays were set up so he could "eat dinner" with his wife, and talk at the table. In the end, he even got a robot self / avatar if I recall correctly, and the question the movie posed was, is that really still him with all these new abilities and scientific ideas, or is the AI abusing their trust in the person that used to be for world domination? Not gonna spoil any details, but the movie was amazing. If anyone knows what it was called, please tell.
