Is there an rpm of GCC 12 (or at least higher than 9) available to download and install, or is it a case of downloading and build from the source yourself?
That's what Software Collections is for.

Specifically you need one of the devtoolset collections - it goes up to 11 which, unsurprisingly, provides gcc-11 on CentOS 7. So:
# yum install centos-release-scl # yum install devtoolset-11 # scl enable devtoolset-11 bash
and gives:
# gcc -v Using built-in specs.
