Okay, I figured this one out myself. Ended up tracking down what VEN_8086&DEV_A0E9 meant. According to the Intel website here: Identify Devices with Errors in Device Manager for the Intel® NUC , it looks like I was missing the Serial I/O driver. I grabbed it from here: Intel® Serial IO Driver for 11th Generation Intel® NUCs . Once I installed this driver I resolved the driver bang in Device Manager and I also got touchpad gestures working on my device. Hopefully this helps someone else out there!
I've been trying to get this exclamation point in Device Manager cleared for a few hours. I've uninstalled/reinstalled drivers, I've restarted, and I've let SupportAssist do its thing but none have resolved the issue. For reference, here is what the driver says: This device is currently waiting on another device or set of devices to start. (Code 51) Dependencies:PCI\VEN_8086&DEV_A0E9&SUBSYS_0A201028&REV_20\3&11583659&0&A9ACPI\INT34C5\2&daba3ff&1   Any ideas on this one?
