Yes, but you can get it inbetween the 1 and the two slot. There's a few ways. Putting something slightly larger (perfectly 2mm) than the gap when it's on setting 1, inbetween, then put it to 2, and close it onto the object. It should stick inbetween. The software adjustments that the quest 2 makes adjust to the position of the screen, not just the 3 defaults. I believe you can also get some sort of 3d printed piece that can hold them at exact IPDs).
In the end, whilst they are almost 4k screens, they're still only a couple of inches from your eyes, and then magnified. You'll also get used to looking by moving your head, rather than your eyes, but the sweet spot on the quest 2 is generally not too bad, so you can use your eyes at least a bit.
