Power Management (& iServices) on Unsupported SMBIOS on latest macOS

Haswell-U's last supported macOS was Big Sur and a MBP11.x SMBIOS, so I installed Sonoma on my laptop using and MBP 14.x SMBIOS (for KBL), because MBP11.x (that had Haswell-U) won't let me proceed with the installer when I first made my EFI.

I am about to do a clean install of Sonoma to fix partition issues, but this time I would like to change the SMBIOS that best corresponds to my laptop's CPU with a "-no_compat_check" boot argument.

I keep seeing everywhere that to "use an appropriate SMBIOS for your setup". Dumb question alert, will using a MBP11.x will still make the PM work on Sonoma?

I am aware that Apple removed a lot of things (like some support to GPUs and WiFi Cards) as they kept releasing new versions, but I am curious about Power Management.

And did anyone got a working iMessage using unsupported SMBIOS using latest macOS versions?
