How to disable special values in options of (combo, richselect)?

For example:
I have a combo like below,

{
    view: "combo",
    id: "test",
    options: [{
        id: 1,
        value: "v1"
   }, {
        id: 2,
        value: "v2"
    }, {
        id: 3,
        value: "v3"
    }]
}

Now, I want “v3” in options is disabled, user can’t select this one, but can see it.
Is there any way to do it?

There’s no built-in solution for such task, but it is possible to add the disabled-like CSS and prevent setting a particular value. Check the snippet:
