You can read linux kernel commit log why this particular change happened. It may have been discussed on the corresponding development mailing lists (which you can find in MAINTAINERS file in Linux kernel sources) and/or LKML and found in archives. This list is the last place suitable for this question. Internal kernel API is changing constantly. There is nothing new.
if I can reenter it and how I can compile nVidia drivers again.
You need to adapt NVIDIA driver to the new kernel API. You may look for changes in 550 series which is compatible with kernel 6.8. It may be enough as long as no modification of closed source part on NVIDIA driver is required.
