This was planned but it's sadly built into the engine in a way that it is not possible. I can reduce the skip chance a bit but 0% or even close to 0% is not possible.
On a technical level, there is a max quality limit on modules of somewhere around 360, with a skip chance of 10% you need 10.0 Quality to get 100% Quality chance, with a skip chance of 1% you need 100.0 Quality, with a chance of 0.1% you need 1000.0 Quality, already being over the limit.
If Factorio allowed full floating point numbers for Quality we could make the chance something ridiculous like 1e-8 where it only creates a higher quality ingredient every 100 million items, but alas that is not possible.
