You could try installing g++-11 and g++-12 (not g++ - this would replace your default compiler) from Debian 12 Bookworm. But do note that it will still replace some gcc libraries with updated versions, which could break your system. Take note which packages are replaced with the updated ones so that you can later downgrade them to restore the system to the previous state. However, if the system is valuable, I would recommend setting up a VM or container with Debian 12 or Ubuntu 22.04 (those have both gcc 11 and 12 in stock repos).
