I managed to snag a new video card with Nvidia's RTX3070Ti. Due to the recent release of the 3070Ti, I have a bit of a problem with Debian 10 as required drivers are quite new (460.84 or 465.31) and Buster has 460.73 in backports. And now Bullseye is frozen so presumably there won't be an update in weeks or months.
On my PC in addition to Debian I have Arch and Windows 10 where new enough drivers are not a problem. As a workaround I set up a two display setup where one display is driven by Intel's integrated and the other by my new Nvidia and that's OK, just in Debian the other display is blank. So what can I do now to get new enough Nvidia drivers? Or actually, is there a documented way for me to create an nvidia-driver package for Buster that I can build and install myself? I don't want to get a PhD in Debian packaging or anything, I guess I mostly want to borrow someone else's recipes on that topic.
