Homebrew installs architecture-specific binaries in different 
hierarchies, /usr/local for x86-64 and /opt/homebrew for AS. Both can be 
installed simultaneously, but each hierarchy is maintained by a 
different instance of the Homebrew software, i.e. /usr/local/bin/brew 
manages x86-64 bottles, while /opt/homebrew/bin/brew manages the AS ones.

In your case, you can do this:

arch -x86_64 bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

to install x86_64 Homebrew alongside your existing AS one, then:

/usr/local/bin/brew install erlang@21

will get you what you want.
