I'm not sure that would work on the 8k
What @Heliosurge is trying to say is the 1060 6g card is not even in the minimum spec, so pimax 8k may not even run as it would fail its min benchmarks.
So it would not be possible to drop the SS I ED as you wouldn't be able to get it to start in the 1st place!
I know what your saying though neal_white_iii ED does allow SS below 1.0 in its graphics setting but that would require you to actually have a hmd running at min spec or above to change that setting.
But in truth, we can't be 100% sure what the final requirement specs are going to be until pimax release them. So here's hoping!
