There is a blog post about using Istio with gRPC proxyless service mesh (including @grpc/grpc-js-xds). As the blog post says, support for this in Istio is experimental and incomplete, so keep that in mind when you use it.

Regarding bootstap files in particular, that blog post says

For gRPC servers, your Pod should also be annotated with proxy.istio.io/config: '{"holdApplicationUntilProxyStarts": true}' to make sure the in-agent xDS proxy and bootstrap file are ready before your gRPC server is initialized.

I also want to note that that blog post says that it supports mutual TLS, but that functionality is not yet supported in @grpc/grpc-js-xds.
