$ brew install python3 --with-tcl-tk
Usage: brew install [options] formula
Install formula. Additional options specific to formula may be appended to
the command.
Unless HOMEBREW_NO_INSTALL_CLEANUP is set, brew cleanup will then be run for
the installed formulae or, every 30 days, for all formulae.
-d, --debug If brewing fails, open an interactive
debugging session with access to IRB or a
shell inside the temporary build directory.
--env If std is passed, use the standard build
environment instead of superenv. If super
is passed, use superenv even if the formula
specifies the standard build environment.
--ignore-dependencies An unsupported Homebrew development flag to
skip installing any dependencies of any
kind. If the dependencies are not already
present, the formula will have issues. If
you're not developing Homebrew, consider
adjusting your PATH rather than using this
flag.
--only-dependencies Install the dependencies with specified
options but do not install the formula
itself.
--cc Attempt to compile using the specified
compiler, which should be the name of the
compiler's executable, e.g. gcc-7 for GCC
7. In order to use LLVM's clang, specify
llvm_clang. To use the Apple-provided
clang, specify clang. This option will
only accept compilers that are provided by
Homebrew or bundled with macOS. Please do
not file issues if you encounter errors
while using this option.
-s, --build-from-source Compile formula from source even if a
bottle is provided. Dependencies will still
be installed from bottles if they are
available.
--force-bottle Install from a bottle if it exists for the
current or newest version of macOS, even if
it would not normally be used for
installation.
--include-test Install testing dependencies required to
run brew test formula.
--devel If formula defines it, install the
development version.
--HEAD If formula defines it, install the HEAD
version, aka. master, trunk, unstable.
--fetch-HEAD Fetch the upstream repository to detect if
the HEAD installation of the formula is
outdated. Otherwise, the repository's HEAD
will only be checked for updates when a new
stable or development version has been
released.
--keep-tmp Retain the temporary files created during
installation.
--build-bottle Prepare the formula for eventual bottling
during installation, skipping any
post-install steps.
--bottle-arch Optimise bottles for the specified
architecture rather than the oldest
architecture supported by the version of
macOS the bottles are built on.
-f, --force Install without checking for previously
installed keg-only or non-migrated
versions.
-v, --verbose Print the verification and postinstall
steps.
--display-times Print install times for each formula at the
end of the run.
-i, --interactive Download and patch formula, then open a
shell. This allows the user to run
./configure --help and otherwise
determine how to turn the software package
into a Homebrew package.
-g, --git Create a Git repository, useful for
creating patches to the software.
-h, --help Show this message.
Error: invalid option: --with-tcl-tk
8.6より低いというか，
$ python3 -m tkinter
で8.5と表示されるので，とりあえず参考サイトに書いてあることをやっています．

==> Dependencies
Required: openssl@1.1 ✔
==> Caveats
tcl-tk is keg-only, which means it was not symlinked into /usr/local,
because tk installs some X11 headers and macOS provides an (older) Tcl/Tk.
If you need to have tcl-tk first in your PATH run:
echo 'export PATH="/usr/local/opt/tcl-tk/bin:$PATH"' >> ~/.bash_profile
For compilers to find tcl-tk you may need to set:
export LDFLAGS="-L/usr/local/opt/tcl-tk/lib"
export CPPFLAGS="-I/usr/local/opt/tcl-tk/include"
For pkg-config to find tcl-tk you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/tcl-tk/lib/pkgconfig"
==> Analytics
install: 4,936 (30 days), 15,421 (90 days), 50,935 (365 days)
install-on-request: 3,009 (30 days), 10,231 (90 days), 36,413 (365 days)
build-error: 0 (30 days)
8.6.9と書いてあるのでアップグレードはできたが反映できていないように自分は解釈しました．
反映させるために，質問のコマンドが必要なのかなと思ったのですが違うのでしょうか？
brew reinstall python3 はうまくいきましたが，
その後に brew upgrade tcl-tk をやっても python -m tkinter で表示されたのは8.5でした．
