OP's issue stems from running Debian, when the supported systems are "RHEL x86 64-Bit" and "Ubuntu x86 64-Bit".

Cursory internet search brings up a Linux review page, where on the first page, it's explicitly stated that to run the cpu, the user is "needing Linux 5.18 + Mesa 22 / linux-firmware.git as of this month to make use of the Radeon iGPU under Linux", and later that "AMD Zen 4 processors [..] are working out-of-the-box on modern Linux distributions like Ubuntu 22.04 and newer."

This is a non-issue.
