The boot loader can only advise the features that were current at the time of release.
If you want newer features then you should install a newer version of the boot loader.

Or edit your config.plist to include the details of more recent firmware.

How would one go about including the details of more recent firmware? Just curious

Also, @chumdoggin I'm sure you tried a system update on the running OS. You could try the opposite, the USB installer. Also, try the latest opencore.
Ultimately, if you wanna skip the troubleshooting and just get it done, you can update to big sur and then Monterey.

You can do it with OpenCore Configurator.
