In theory yes, but in practice it’s not too bad. Especially with Rust, or even Nim NIFs.
It’s only a problem if the NIFs crash (rate in my experience), or they take too long and cause the VM to hang (easier to do for big computations). Now with the newish ability to mark a nif as dirty which helps the scheduler know a nif can have longer runtimes that could block the VM.
P.S. Elixir/BEAM often also achieve resilience via connecting multiple nodes as well.
