This CPU is very old. It is unlikely that it supports x86-64-v2. I would attempt to boot up any live image of any enterprise linux (rocky linux, alma, euro if they have it, etc) and verify it by running: /lib64/ld-linux-x86-64.so.2 --help
At the bottom of the output, you should see something like this:
Subdirectories of glibc-hwcaps directories, in priority order:
x86-64-v4
x86-64-v3 (supported, searched)
x86-64-v2 (supported, searched)
If x86-64-v2 does not show as supported, you will not be able to install nor run any Enterprise Linux 9 distribution (this means rhel, rocky linux, eurolinux, almalinux, oracle linux)
