The dns-resolver and routes are incorrectly placed behind the networkConfig section in the provided configuration example.

According to the documentation titled Optional: Configuring host network interfaces for dual port NIC, the networkConfig field contains information about the network configuration of the host, with subfields including interfaces, dns-resolver, and routes (read point 1). However, the provided example placed the dns-resolver and routes configurations behind the last bond interface configuration. It should be placed behind the networkConfig, so two spaces before.

Please also review the documentation provided at point 2 under Configuring host network interfaces for subnets.
