Updated nvidia-installer to select the NVIDIA open GPU kernel modules by default on systems with GPUs that support both the proprietary and open kernel modules.
In Bazzite, you should just need to open the Discover package manager and click "Refresh" and then "Update All" in the top right. Although these drivers don't appear to be available through the package manager yet; mine is still on version 560.31.02.
