Opensearchknn_faiss_avx2.so are not delivered as part of 2.19.x opensearch

Plugins k-NN

Versions (relevant - OpenSearch Plugin): 2.19.x

Describe the issue: opensearchknn_faiss_avx2.so is not delivered as part of 2.19.x series,
some environments expect .avx2 files instead of faiss.so files.
Hence, the basic deployement itself failing if KNN plugin is enabled during opensearch installation phase.

Could you please explain is there is any workaround for 2.19.x series to work for avx2 cpu machines.

Configuration: Opensearch KNN plugin enabled with 2.19.2
