Here's the OpenCore 0.7.4 config I made based on Jake Lo's, currently running macOS Monterey 12.0.1 without any issues. FYI my E7270 has a Broadcom BCM94360 for the wireless card and ALPS V8 for the touchpad, so change whatever is needed for your version. Some models apparently come with ALPS V7 in which there's a driver by Skyrilhd that has better multitouch features.
