It you run Debian and need v455 Nvidia drivers; then it looks like 
you'll need to either build the drivers yourself or run Sid with 
"experimental" enabled (or some other edgy set up)!

Nvidia v455 drivers (455.23.04-1) appear to only be in "experimental" at 
this time[1].

[1] https://packages.debian.org/experimental/nvidia-driver

Seeing as Buster backports come from testing (Bullseye), which in turn 
come from unstable/Sid and both of these only have 450[2][3], I imagine 
that it will be a few weeks at the absolute soonest before there will be 
an option to backport to Buster.

[3] https://packages.debian.org/sid/nvidia-driver

Having said that, I suspect that the reason why they are in experimental 
is that the current v5.9 kernel (as per what is currently default in 
Sid[4]) is incompatible with Nvidia drivers[5]. So until Nvidia fix 
their drivers and do a new release, you'd need to use an older kernel. 
TBH, I'm not really sure what your options will be there?!

Personally, until Nvidia stop being so sucky towards open source and 
Linux, I'd recommend avoiding Nvidia hardware wherever possible.

It does sound like in your case it might be a little too late though?! 
Perhaps you can contact the vendor and see if you can return it and swap 
it for an AMD card?

Good luck regardless.

Cheers,
Jeremy
