¿Hacer que brew utilice el curl instalado por brew en lugar del curl del sistema?

He instalado curl 7.77.0 con brew, pero cuando voy a instalar otras cosas con brew falla en la descarga de algunas cosas porque está usando la versión del sistema de curl que es 7.43.0. ¿Cómo puedo hacer que brew utilice la versión posterior?

brew config

If you need to have curl first in your PATH, run:
  echo 'export PATH="/usr/local/opt/curl/bin:$PATH"' >> /Users/Admin/.bash_profile

For compilers to find curl you may need to set:
  export LDFLAGS="-L/usr/local/opt/curl/lib"
  export CPPFLAGS="-I/usr/local/opt/curl/include"

For pkg-config to find curl you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/curl/lib/pkgconfig"

cat .bash_profile

export PATH="/usr/local/opt/curl/bin:$PATH"
