Latest 5.10 tickless kernels (5.10.14) available here:
The "client" kernel is fully pre-emptive with a 1000HZ clock, the "server" is non-preemptive with a 100HZ clock. Client kernels are optimized for lowest possible latency, server kernels are optimized for highest work throughput.

There are three '.deb' files in each, download all three then install with:

dpkg -i *.deb

They can be remove with apt same as any other .deb package. These will work on any debian based distro, Ubuntu, Debian, Mint, Zorin, MxLinux, Julinux, etc.
