It is indeed possible with hunspell, as Eli mentioned. I use the
following settings for this:

#+begin_src emacs-lisp
(use-package ispell
  :custom
  (ispell-program-name "hunspell")
  (ispell-dictionary "en_US,pt_BR")

  :config
  ;; from https://emacs.stackexchange.com/a/21379/18951
  (ispell-set-spellchecker-params)
  (ispell-hunspell-add-multi-dic "en_US,pt_BR"))
#+end_src

It works very well for me.

You might interested in a recent thread about spell-checking at Reddit:
https://www.reddit.com/r/emacs/comments/fxs92h/spell_checkers_in_emacs_in_2020/

Using multiple dictionaries was also discussed there.  In particular, I
received nice tips from Alan Third on how to fine tune hunspell for the
case quote contractions (common in English) with curly quotes and
multiple dictionaries.

HTH,
Gustavo.
