Using Mac Mini M1 with latest Ventura OSx. I have downloaded Monterey from App store to install on an external SSD. Mac wont let me open Monterey to install on SSD as I am in a newer OSx (Ventura).
Please advise.
Mac mini, macOS 13.3
You have to create a Monterey USB Bootable Installer, boot from it then install Monterey to the external drive.

1 - It is suggested to Create a Bootable Installer of Monterey
2 - Once that is achieved , the user will be required to change the Startup Security on this Apple Silicon Computer.
3 - About Startup Security Utility on a Mac with the Apple T2 Security Chip - Apple Support
3 - This will ALLOW the user to Boot From the Monterey Bootable Installer created in the previous step
4 - Boot into the Bootable Installer drive and direct the Installation to the Desired External Drive
EDITED
Monterey wont open in Ventura
