All new drives need to be formatted before you can do anything...erase/format/initialize

Erase and reformat a storage device in Disk Utility on Mac

note: Failed to Install Monterey —This is a known issue— non OEM Apple NVMe / PCIe SSD

The work around is to reinstall the OEM Apple Drive upgrade that drive which will flash the board, then reinstall your third party drive and now you can run the installer on your machine.

The EFI /Firmware part of the Monterey pkg is verifying for OEM Apple Drives and fails to upgrade. The EFI boot ROM is required to Flash the board and is required to successfully install Monterey.

Your hard drive has nothing to do with being compatible with Monterey or not.

So what year and model is your device? check the article above your name to see if it is compatible.

I understand I need an original Apple one to install Monterey then reinstall my ssd to do it but is there another way, or should I purchase one to do it?

thanks
