Hi, I observed the same behavior with grpc-1.28.1. Tensorflow builds fine with grpc-1.26.0. I also found bugreport https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239185
Breaks on AMD64, had to downgrade to grpc-1.26.0 to have it compiled which is now working on NVIDIA GeForce video cards.
Can you try TF-2.3? It builds against grpc-1.28 on all my systems now. please re-open if there are still issues
