I only use Debian (or Debian derivatives) and it ships (since at least version 10 of Debian) with a RT kernel which you can install. It is described as: "This kernel includes the PREEMPT_RT realtime patch set." So I take it it's still a patch not part of mainline yet? Out of curiosity I tried it: https://packages.debian.org/bullseye/linux-image-5.10.0-20-rt-amd64 https://packages.debian.org/bullseye/linux-image-5.10.0-20-r... ... but only to be met with NVidia drivers telling me they cannot patch real-time kernels! Didn't look more into it: it's maybe easy to solve.
