Is it possible to enable the cgroup rt support in Debian Buster (kernel 4.19.0) without recompiling the kernel? Perhaps with a grub configuration parameter? Thanks.

Background: Docker logs this warnings:

Your kernel does not support cgroup rt period
Your kernel does not support cgroup rt runtime

You need to install a realtime kernel.

eg.

$ sudo apt install linux-image-rt-amd64

You'd need to move away from the 4.19.0 kernel anyway, also because it is buggy in handling >8 network streams in its vxlan codepath.
