The only way you can not be judgmental is by being dead or unconscious. Living is about making judgments about everything, all the time (and most of them become habits at some point).
A person may not be able to suppress spontaneous judgement, but one can observe the process and reflect on the reasoning, incentive, and emotions that go into it afterwards. Then you can decide if you mind _should_ be made up, or if it might be better to put more effort into a higher order of understanding.
I once heard this observation: judgement and curiosity are two distinct states of mind. If you’re curious about something, you cannot simultaneously be judgmental.
