+The Quadro RTX 8000 is supported (well, not really on ARM64) by both Nvidia's proprietary driver and the open source Nouveau driver in the Linux Kernel.
+
+It will require a 1x to 16x adapter, or some other means of adapting the 16x-sized card pins into the 1x slot on the CM4 IO Board. You also need to supply at least 300W through the card's two PCIe power plugs.
+
+There are two ways to try installing the driver:
+
+### Proprietary Nvidia driver
+
+After flashing the 64-bit Pi OS beta to my Pi, I made sure to upgrade everything on it, and install the kernel source, so the Nvidia driver would compile:
+
+```
+sudo apt-get update
+sudo apt-get -y dist-upgrade
+sudo apt-get install -y raspberrypi-kernel-headers
+sudo reboot
+```
+
+After rebooting, if you have X server running (e.g. you are logged in via GUI), you need to log out. If you're running this over SSH or serial connection, you can quit X server with: `sudo systemctl stop lightdm`.
+
+Now, download Nvidia's latest [AARCH64 Driver for ARM 64-bit processors](https://www.nvidia.com/en-us/drivers/unix/linux-aarch64-archive/), make the downloaded `.run` file executable, and run it with `sudo`:
+
+```
+chmod +x NVIDIA-Linux-aarch64-525.89.02.run
+sudo ./NVIDIA-Linux-aarch64-525.89.02.run
+```
+
+> Note: I had to select 'show all OSes' when downloading the driver, to get the arm64 version—it seems like ARM64 is not a supported platform for the Quadro RTX 8000.
+
+When I tried starting Xorg (with `startx`), I got a few errors and it would not launch. Luckily, the system didn't lock up, so that was nice.
+
+The USB-C port on the back seemed to work, at least at USB 2.0 speeds. I plugged in a couple devices and they were immediately recognized by the Pi.
+
+### Nouveau (open source) driver
+
+To get the Nouveau driver loaded, you have to [recompile the Linux kernel for Pi OS](https://github.com/geerlingguy/raspberry-pi-pcie-devices/tree/master/extras/cross-compile).
+
+Go to `Device Drivers` > `Graphics support` on the `menuconfig` step, and select the `Nouveau` driver to install.
+
+If you want to be able to boot the Pi all the way, make sure to blacklist the `nouveau` kernel module:
+
+```
+sudo nano /etc/modprobe.d/blacklist-nouveau.conf
+
+# Put this inside the file and save it:
+blacklist nouveau
+```
+
+Now, after a reboot, you can explicitly load the module and see what happens by following `dmesg` in another terminal session:
+
+```
+sudo modprobe nouveau
+```
+
+When I tried this, I got a kernel panic, but the Pi didn't lock up completely. I couldn't get past this stage due to memory access errors.
+
+See the linked GitHub issue for more details.
