Builder config for ssh certs or for insecure remote registry pull

[suityou01]

My command

docker buildx build --platform linux/arm/64 -t 192.168.1.5:443/bpmcore_openid_provider_storage:2 . --load

Is failing with

error: failed to solve: rpc error: code = Unknown desc = failed to solve with frontend dockerfile.v0: failed to create LLB definition: failed to do request: Head https://192.168.1.5:443/v2/cbslabs/rejson/arm64/manifests/1: x509: certificate signed by unknown authority

How can I configure an insecure remote registry for the builder?

Configure registry exceptions in buildkit config file https://github.com/moby/buildkit/blob/master/docs/buildkitd.toml.md and set it with --config on buildx create

Is there any useful and complete documentation on setting up buildkit with non-public certs?
