Is it possible to specify the command that gets executed when deploying a configuration?

[mainrs]

I use microvm.nix in an imperative way without flakes and using npins and nilla.dev. The deployment of the microvm to the host that runs it involves two commands:

nix run --file ./nilla.nix systems.nixos.microvm.result.config.microvm.deploy.installOnHost user@host
ssh user@host -- systemctl restart "microvm@microvm.service"

Can something like this be configured for colmena? I could not find any options related to this! Thanks!

This is not a support forum, but yes this is a NixOS feature. Add the script to system.activationScripts and it'll run on the node you're rebuilding.
