Try booting into Internet Recovery Mode using Command + Option + R to see if it will access the online macOS 12.x Monterey installer. Unfortunately regardless of the keys used for booting, some Macs may only boot to the older online installer for the OS which originally shipped with the Mac from the factory.


Otherwise you will need access to another compatible Qualifying Mac in order to create a bootable macOS USB installer using the instructions in this Apple article:
