Should we use SSG for deploying a dashboard created using Nuxt.js?

We are going to develop a dashboard for internal use using Nuxt.js. As this will be an internal dashboard there is no need for a universal mode. Generally most of the dashboard are developed in SPA.

But SPA also requires a server to send the initial HTML and js bundle to the browser. So what if we use SSG and deploy it to s3 as it will no longer need a server and we can save the cost?
