I have gotten an EFI with OpenCore capable of loading Catalina 10.15.7 and also the final version of Big Sur 11. When I load Catalina the graphic acceleration stops working but everything else works correctly, wifi, bluetooth, sound, etc. With Big Sur I don't have graphic acceleration either, so the touch screen doesn't work either. The trackpad doesn't recognize it as such, but I can still perform all the normal gestures.
During installation, it is not necessary to use an external mouse, as the trackpad or touchpad works perfectly.
With this OC EFI therefore, it would be possible to perform a direct update from our latest version of Catalina 10.15.7 to Big Sur 11.
I leave a test capture:

Let's see if someone cheers up and finds how to fix the graphical acceleration and with it also the sleep mode.
In order to use the intel hd 620 graphics of the equipment, I had to use the AAPL, ig-platform-id recommended by dortania and perform a spoof with the device-id:

I bring news, with the latest EFI that I am going to attach, Catalina 10.5.7 can be loaded perfectly but the trackpad does not work, although it can be used provisionally until we update the macOS to the new Big Sur 10.0.1 version. Graphics acceleration doesn't work either, so neither does the touchscreen. Everything else works perfectly.
Once we carry out the direct update if you want or a new one from a bootable usb with createinstallmedia with the latest version of Big Sur, everything works in this EFI except the graphics acceleration with the intel hd 620, the igpu, that is, Wifi works and bluetooth (I replaced the dual wifi + bluetooth module that the computer has with a BCM94360NG module, so that the drivers are natively accepted), the battery measurement, the trackpad, the sound, the DRM, AppleStore, iMessage and FaceTime. Attached some screenshots:
Note: let's see if someone cheers up, and finds a fix for the graphics acceleration of the intel hd 620 with OpenCore 0.6.4 in macOS Big Sur 11.0.1 and if it gets it, please post it.
