Perhaps a bit overkill but I'm not too sure how to override a Nixos service's parameters.
Essentially the default options are in .../jvm.options so I copied the elasticsearch.nix from Github and modified the following:
${optionalString es6 "sed -i '/-Xms1g/d' ${configDir}/jvm.options"}
${optionalString es6 "sed -i '/-Xmx1g/d' ${configDir}/jvm.options"}
Along with changing the name of the service (otherwise I'd assume it would conflict). I then just included this nix expression into my config and it seems to be working with the appropriate values set in ES_JAVA_OPTS.
