Most likely you have the mitigation already in place, that is disabeling the XTheadVector extension.
The regular distributions don't enable it, since it's a non standard incompatible vendor extension based on a draft spec. When I wanted to benchmark their implementation last year I patched a kernel to enable it, and needed to consult the open source part of the core [0] to figure out that they placed the enable CSR bit in a different location than the final ratified spec.
