Basically root volume patching for systems having no metal enabled GPU is still in the public beta phase with Big Sur. I am not quite sure if it will work straight ahead on Monterey in the same way it does with the recent version of Big Sur. For that reason it might have been blocked.
If you are using OCLP it will be printed to the screen while creating the configuration. You can also open the EFI partition of your system and search for the config.plist and read the first few lines:

Installation of 12.0 beta on a MBP5,2 in progress.
To be able to enjoy all of us
Thanks Alphascorp. Installation ran without problems.
Hurrà!
In my 27 '' late 2013 iMac (i7 CPU - 24GB RAM - nVidia GTX 780M 4GB) Monterey works better than Big Sur!
Who says Apple has ruled out nVidia cards in macOS 12?... With Big Sur I have never been able to get Photo Booth to work and it took several changes to the OpenCore Legacy Patcher before my films were working in Apple TV... (@Ausdauersportler and @khronokernel know this well ...)
As soon as I installed Monterey, instead, my iMac started working completely fine, as if macOS Catalina had been installed and not a Beta of two successive Systems...
This means that Apple shouldn't have ruled out my iMac from Big Sur and laters.
Even in what I add below, apparently O.T., it suggests that many aspects have been overlooked in Big Sur to entice many of us to switch to the new iMacs. I was about to do it, until a few minutes ago ... Thanks Monterey and thanks MacRumors!
O.T. but not too much...
Regarding planned aging, my iMac was just dead, some days ago, since the hinge broke. Well, I repaired it by replacing the two PLASTIC washers with a metal rod that could never, ever give way under the pressure of the two springs... But if you saw the two plastic washers that have given way and how thin they are, you would understand that have been purposely designed to fail after a number of years...
The hinge, in fact, is wonderfully engineered, which means that it has been calculated based on weight and function. Nothing would have been simpler, therefore, to use either two metal washers or, better still, a single metal bar (with two holes for the two screws), as I maked.
Instead, two plastic washers were intentionally designed and made, at the cost of making the fabrication more complicated and a little more expensive.
From my point of view it is either pure nastiness or some bad Engineer may have acted in bad faith, despite being very good at knowing how to design this splendid hinge. If there had been Steve Jobs, in this case, this person would have stopped working all over the world. Therefore it is legitimate to suspect that someone from the Marketing has deliberately ordered to plan the failure after a few years from the expiry of the guarantee.
I.T.
Now, however, since the hinge has been repaired perfectly, I have stopped considering the purchase of the new iMac. Then, I will continue to use my iMac, noting that it has never worked so wonderfully well since I bought it.
Of course I'd buy a new Mac if I needed better performance for videos and more.
Yes I upgraded the cMP5.1 WiFi card with BCM94360CD, so I don't need to add kexts.

fiif echo $SVPL_BUILD | grep -q '^20'Well, I copied the kexts directly with BigSurmountsrw, then clicked Rebuild KC, rebooted and it works. Thanks.
Update: I just got a "new" cMP3,1 with a Broadcom BRCM94321 Wifi module in it. With this module, the system boots fine, but of course due to unpatched 80211 kexts Wifi does not work yet. But this might be helpful in finding the drastic reset/reboot behaviour of the three other types of cards (see original post).
