If you use nix-bitcoin you can run Bitcoin Knots as alternative to BItcoin Core.
Just edit the configuration.nix file and add:
--------------------------
services.bitcoind.package = let
pkgsUnstable = import (builtins.fetchTarball {
# nixpkgs-unstable as of 2023-12-12
url = "https://github.com/NixOS/nixpkgs/archive/666fc80e7b2afb570462423cb0e1cf1a3a34fedd.tar.gz";
sha256 = "1j4ahdm49pbw5s1sw0vc0l12s1zxlnw0sjvnljxhdjbsvgbjsl7m";
}) {};
in
pkgsUnstable.bitcoind-knots;
