How can I pipe from shell to a scratch buffer (without file)?

Assume we have the following lua function to create a non-file backed buffer:

M.makeScratch = function(scratchpath)
  local uri = vim.uri_from_fname(scratchpath)
  local bufnr = vim.uri_to_bufnr(uri)
  vim.bo[bufnr].bufhidden = ""
  vim.bo[bufnr].buflisted = true
  vim.bo[bufnr].buftype = "nofile"
  vim.bo[bufnr].readonly = false
  vim.bo[bufnr].swapfile = false
end

Now assume there is shell opened and the uri + buffer number is known (can be found via scratch path).
How can I pipe a command output to the created scratch buffer (not backed by a file)?

I don’t have a complete answer, but I’d use the client-server feature of Neovim to pass the --listen option to the Neovim instance that creates a buffer, then run a command to pipe stdin to the server.
