I have a layer of approximately 2M point features from which I need to create a second layer, only including the points that are not within (or bordering on) a set of polygons that are saved in another layer.

Can QGIS handle this? Extract by location seems to only include options if you want to keep the points that are within other polygons.

I'm using QGIS 3.14

The tool you are looking for is Processing > Toolbox > Vector selection > Extract by Location, using the Disjoint option:

The Help page describes the tool quite well.

    I keep a copy of 2.18, and disjoint is also available there.

You could use the select by location tool, select all points within the polygons and then reverse the selection. Though I don't know how the tool handles datasets this large.
