I ran into this problem recently and there isn’t a clean way to do it.
The best solution in my experience is to define a pad using the “Add Pad” button.
Then set:
- Pad type: “NPTH, Mechanical” (Non-Plated Through-Hole)
- Pad shape: Circular
- (Pad) Diameter: your target hole diameter
- (Hole) Diameter: your target hole diameter
It’s kind of hacky to have to define a pad where you don’t actually want one, but this is just how it is.
For reference, the standard library does this too: MountingHole:MountingHole_2.1mm
