I have a news website project where I need every page to be Statically generated. I have a singles file with all my requests encapsulated in server actions. This uses a custom db connection:

import { payload } from '@/payload/lib/client';
import jsdom from 'jsdom';

// import { unstable_cache } from 'next/cache';

export async function get_global_config() {
  'use server';

  const global_config = payload.findGlobal({ slug: 'general-Website-Config' });

  return global_config;
}

export async function get_steam_count() {
  'use server';
  const steam_counter = await fetchData()

  return steam_counter;
}
[...]

How do I cache this in order to get static data? I only want to revalidate it on the next build. Is unstable_cache the way to go?
