Using Node 20 with AWS Amplify

[iwbc]

Describe the feature

I have deployed Nuxt to AWS Amplify and the runtime seems to be running on node 18.
In the source code, 18.x is specified as follows, which could not be changed in the config on the Nuxt side.
Is it possible to improve this so that it can be changed on the Nuxt side?

computeResources: nitro.options.static
      ? undefined
      : [
          {
            name: "default",
            entrypoint: "server.js",
            runtime: "nodejs18.x",
          },
        ],
