The system wants to install the last OS you had. If you have an Intel Mac and you want to install the OS that came with your Mac then you need to boot into recovery a different way. See the attached process at the bottom:

The Recovery Volume of this computer has been updated to Monterey


If the user wants to Roll Back from Monterey to Big Sur >>


Scorched Earth Method 


This method will WIPE ALL Data and there is No Recovery - Period.


>> Only works on Intel Based Apple Computer <<


To perform this action will require booting from a Bootable Installer


The Bootable Installer can Only be performed on an Apple Computer 


This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer. Example : Bootable Installer of Big Sur would have to be done on a computer that Qualifies to run Big Sur.


Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can not be used.


Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.


Extra Special Notation regarding the Touch ID equipped Apple Computer.
