Post multiple Metafields with one call into Shop

I see where we can query the shop metafields, like this. But not where there’s any mutation to add/modify them?

{
  shop {
    id
    metafields(first: 5) {
      edges {
        node {
          id
          namespace
          key
          value
          valueType
        }
      }
    }
  }
}
