Get entitlement error when using host network

I'm trying to build an image using host network, but get the following entitlement error. I can build using the standard docker build command with host network, so I'm not sure what is the cause of the error.

error: failed to solve: rpc error: code = Unknown desc = granting entitlement network.host is not allowed by build daemon configuration

Here is the command I use to build:

docker buildx create --name test --platform linux/amd64,linux/arm64 --driver docker-container --driver-opt "image=moby/buildkit:master,network=host" --buildkitd-flags "--allow-insecure-entitlement network.host" --use docker buildx build --allow network.host --network host --builder test --push --build-arg VERSION=673cda6 -t test .

Here is the docker and buildx version information:

docker buildx version
github.com/docker/buildx v0.5.1-docker 11057da37336192bfc57d81e02359ba7ba848e4a

Start with the reported docker buildx create and docker buildx build commands, then trace how the network.host entitlement and --allow-insecure-entitlement network.host settings reach the build daemon. Reproduce the error with the stated Docker and buildx versions; done means identifying the configuration mismatch or documenting the required setup for a successful host-network build.
