Multi select dropdown, hide values if one option is selected

I have a multi select dropdown which has 4 values, say Value 1, Value 2, Value 3, Value 4. Users should be able to select multiple options of course, such as Value 2 and Value 4; however, if the user selects Value 1, then I want it to be impossible to add any others.

So Value 2, 3 and 4 can all be single, or a combo, but Value 1 should always be the only option if it’s selected. Is there any way to do that? I tried doing conditional on the multi select dropdown and put if the value contains Value 1, but under the actions it didn’t seem like there’s an option to have the condition then hide options. Thanks!
