This is what I have in my Emacs init file:
(add-hook 'elixir-mode-hook
(lambda ()
(add-hook 'before-save-hook #'lsp-format-buffer nil t)))

Not specific to doom, but you can use poly-mode to combine web-mode and elixir-mode to accomplish this:
(use-package
polymode
:ensure t
:mode ("\\.ex\\'" . poly-elixir-web-mode)
:init (setq web-mode-engines-alist '(("elixir" . "\\.ex\\'")))
:config
(define-hostmode poly-elixir-hostmode :mode 'elixir-mode)
(define-innermode poly-surface-expr-elixir-innermode
:mode 'web-mode
:head-matcher (rx line-start (* space) "~H" (= 3 (char "\"'")) line-end)
:tail-matcher (rx line-start (* space) (= 3 (char "\"'")) line-end)
:head-mode 'host
:tail-mode 'host
:allow-nested nil
:keep-in-mode 'host
:fallback-mode 'host)
(define-polymode poly-elixir-web-mode
:hostmode 'poly-elixir-hostmode
:innermodes '(poly-surface-expr-elixir-innermode)))
my full init.el is here if anyone is interested:

Doom Emacs now supports tree-sitter. Have restructured my config (Org mode ftw!) and will soon update the topic start post.

Did you manage to make tree-sitter work to correctly syntax highlight HTML code inside ~H ~F and ~L sigils?

Not yet, but that is the main reason the opening post has to be updated as Doom Emacs does not work that well with Phoenix projects.

Due to Emacs not doing great with a professional project I have to work on at a daily basis; I have to postpone my usage of Doom Emacs. As a result I won’t be able to keep the opening post as updated as it should be.
Please drop me a message when you are able to maintain the opening post.

I still use CentaurEmacs (even though I already use LunarVim for most of of my development) and it is doing surprisingly well, has good errors and warnings detection, for Elixir and Rust both it does linting with dialyzer and clippy respectively, shows docs on autocomplete and sometimes when you put cursor under a thing.
It works much better than I expected. Even with that I get the occasional lockups for 2-3 secs.
Haven’t checked how well it integrates with Phoenix though. I suspect not well but if you’re curious and have time you could give it a go. It’s based on Doom Emacs.

A bit of a necro, but I’ve been using Doom for a while. And I use Emacs for almost everything - The Way of Emacs .
Been using alchemist since 2016 and just upgraded to use eglot and elixir-ls. It’s much better than alchemist and eglot will ship by default with Emacs 29.
Configuration below:
packages.el
(package! elixir-mode)
(package! eglot)
(package! exunit)
(package! inf-elixir)
config.el
;; eglot configuration
(use-package elixir-mode)
(use-package eglot)
(use-package exunit)
(add-to-list
'eglot-server-programs
'(elixir-mode . ("sh" "/home/YOUR_HOME_DIR/.elixir-ls/release/language_server.sh")))
(add-hook
'elixir-mode-hook
(lambda ()
(subword-mode)
(eglot-ensure)
(company-mode)
(flymake-mode)
(add-hook 'before-save-hook 'eglot-format nil t)
))
(setq inf-elixir-project-command "iex -S mix phx.server")

I’ve also been using the Elixir mode with Treesitter support for while now, as Emacs 29 will come with support for it.
I really like it.
