Uma informação que encontrei:
So I have switched to Clover (for the Trackpad sake) and created my own patches for the Trackpad and it works perfectly now! VoodooI2C is now able to detect my Trackpad, its pinning and now works under Interrupt mode, rendering a more stable experience (see screenshots below). The laggy cursor bug I mentioned above occurs very slightly to me now, although all 2-finger gestures (like zoom, rotate) are still a hit-or-miss to me: they basically work, but not smooth. Also I have the same Trackpad as yours (Dell 081C) and my BIOS version is 1.13.1 (Downgraded from v1.14 because of undervolting issue).
Here's my theory for the Trackpad bug under OpenCore (I'm assuming you're using SSDT patches and not directly edit and compile your DSDT): those SSDT Trackpad patches are used to patch
