I am trying to connect the second NIC in two servers directly using a crossover cable. I want to setup a direct 10G connection for DRBD.

Have you actually tried the connection and verified that it doesn't work? As a general rule, almost all modern GbE and higher speed NIC's implement auto MDIX, which means not only that you normally don't need a crossover cable with them, but that they also shouldn't care if you do use one.

I have tested the crossover cable on two Windows systems and have verified it works. I have the primary NIC's on the two Ubuntu servers connected via a switch and they communicate fine. I cannot ping the IP of the secondary NIC (connected via crossover cable) from the other server(s). I don't know how to setup the direct connection on the secondary NIC's in netplan.

Have you configured static IPs for the relevant interface devices on both ends (or set up a DHCP on one end)?

I have tried configuring static IP's, but I don't know all of the necessary parameters. Below is my current 01-netcfg.yaml file. en02 is the interface connected with the crossover.
