You could:

   - install bookworm in a VirtualBox virtual machine and
     deploy your application: that would be the safest
     and simplest way with a bookworm (12) virtual machine

   - try to install the linux kernel manually on your buster (10),
     this might break things

   - deploy your application in a Debian buster (10) container on a
     LXC or Docker bookworm host: this might create problems as some
     kernel ABI might have changed

Typically, I was unable to install a bookworm container on a buster host kernel
(reverse problem you want to try), but bullseye and bookworm containers seems
to work on a bullseye host.

A loooong time ago, I had to fix a problem like this with a LD_PRELOAD, until
full upgrade was possible.
