Debian Buster backports Nvidia driver dependency hell.

I would like to install the XanMod stable real time kernel (linux-xanmod-rt metapackage). However, despite my having buster-backports in my sources.list, apt doesn't seem to draw in the backports Nvidia driver. On a reboot, the boot up process stops with a blinking lower case sursor. Therefore, I try to upgrade manually:
Code:sudo apt install nvidia-driver/buster-backportsThis unfortunately leads to dependency hell:
Code:$ sudo apt install nvidia-driver/buster-backports

E: Unable to correct problems, you have held broken packages.I want to use my computer for music production, thus the real time kernel, but as you can probably tell, I am completely new at this and don't really know where to go from here...
