I have a Eaton HS Supercapacitor that is rated at a maximum of 3.8V, but I noticed on the data sheet there is a "Minimum working voltage 2.2 V". Will using the capacitor to power a boost converter that will drain it below 2.2V be damaging to the cap?

Eaton HS model is not a regular supercapacitor, but it is a hybrid supercapacitor.
It is a hybrid of regular supercapacitor and lithium-ion cell.
So same restrictions apply due to the lithium-ion cell technogy - the lithium-ion part of the hybrid capacitor will get damaged when it is discharged below safe voltage.
