In JoJo's Bizarre Adventure, I've been wondering why, when a person's Stand is getting hit, they don't just unsummon it.
Can Stand users de-summon their Stand whenever they want?

Maybe if a stand has hold of another stand, I do not believe it can be taken back.
Example 1: Kakyoin's Hierophant Green stuck in Strength in Part 3.
If you felt like you were being punched in the stomach, I don't think you would be able to run. Simply, the answer is no, because you would be in pain.
It is similar to stands, as stands are a physical manifestation of the soul, and they're practically just 'another body'.
Also removing your stand in the middle of a fight would be suicide.
For example, Hanged Man and Emperor did damage to people's actual bodies without touching their stands.
First, I disagree with the premise that a Stand user would want to de-summon their Stand in response to it taking a hit, for the same reasons that Palkia Catcher already covered. One comment I'll add: if the Stand's reaction time is fast enough to notice an attack about to land, the Stand could probably dodge or block instead.
While I can't point to any explicit rule that a Stand must return to its user before disappearing, I can think of several situations where being able to instantly recall a Stand would be extremely useful to the user but they don't do it, implying that Stands don't work that way:
They can't de-summon it mid-combat for, well, y'know, reasons. I don't think you'd be able to just 'abracadabra' something connected to your body for spiritual reasons.
It's like stand users using their stand abilities, they have to consciously use it without being distracted.
TLDR: no because funny brain
