Opencore with Tianocore on T440p?

I have successfully installed macOS Monterey on my ThinkPad T440p using Opencore on the stock BIOS. However, I'm facing issues after switching to Coreboot/Tianocore. I assume my SSDT only working on stock bios. I was wondering if anyone here has successfully installed a Hackintosh with OpenCore on top of Coreboot/Tianocore.

I'm wondering if there's something specific I need to do in order to get OpenCore to work with Coreboot/Tianocore. Any help or guidance would be greatly appreciated.

Thanks in advance!
