Kubernetes nodes - unable to create wireguard in the Pod

I use the Digital Ocean managed Kubernetes cluster and would like to create a wireguard interface.
For the command
wg-quick up wg0

the error message is ‘RTNETLINK answers: Not supported’.

How would I go about getting a node that has the support for the wireguard kernel module?

We currently run a debian-maintained Linux 4.19 whereas the in-tree wireguard didn’t make it into the kernel until 5.6. We’re currently looking into upgrading to Linux 5.7 which is consideration to be released soon.
