Install curl via that script from the latest git repos

brew install --HEAD -s curl.rb

Tell your cli to use the curl version just installed (if you're using zsh, othwerise you might need ~/.bashrc)

echo 'export PATH="/usr/local/opt/curl/bin:$PATH"' >> ~/.zshrc

echo 'export PATH="/opt/homebrew/curl/bin:$PATH"' >> ~/.zshrc
