Using LibreSSL 3.1.1 without messing with the system

I did a brew install of OpenSSL/LibreSSL (3.1.1)... it's located in /usr/local/opt/libressl/bin/openssl I also have the usual macOS Catalina OpenSSL/LibreSSL bin at: /usr/bin/openssl I don't wanna mess with the system. I know brew says it's keg-only and not symlinked into /usr/local. This makes sense to not mess with system openssl calls. Can I do my own alias to the /usr/local/opt/libressl/bin/openssl latest version with something like: alias libressl="/usr/local/opt/libressl/bin/openssl" in my .zshrc so that I can use libressl 3.1.1 for one off command line things without messing with my macOS system stability?
