I don't use Kali Linux, but it sounds like it's based on Debian's testing release. Debian hasn't packaged Blackwell drivers yet, so I wouldn't be surprised if Kali doesn't have them packaged either. You can download Blackwell drivers from Nvidia, but the Debian guys won't have made sure that things don't break with them.
https://wiki.debian.org/NvidiaGraphicsDrivers
https://www.nvidia.com/en-us/drivers/details/259042/
I don't know why you wouldn't be able to install the driver with the graphics card inserted.
The initrd contains drivers that aren't directly built into the kernel.
Typically, the way this works on Debian with third-party drivers is that you have the proper linux-headers package matching your current kernel installed. Then a third-party package registers a DKMS module with the driver source, and when you install a new kernel, the driver gets recompiled for that kernel. That driver gets dropped into the initrd, the ramdisk with the out-of-kernel stuff required to boot.
I don't use Nvidia hardware, so I can't tell you if that's what's supposed to happen, but I would guess so.
If you're not booting with it, my guess is that something isn't working as part of that process. Either the Nvidia script didn't register the module or it didn't get rebuilt or the installed driver has some issue and isn't working when you try to load it.
You can probably run
sudo dkms statusand it'll show DKMS modules and their current status. That might be a starting point.
