Present simple for future events

[Marcin]

Hi,

I'd like to ask about the following sentence:
What have you decided to do tomorrow?

I was wondering if it is possible to use present simple to deliver the same meaning? Like this:
What do you decide to do tomorrow?

Just like we use present simple to talk about future events. For example:
What time do you finish work tomorrow?

Can we use the word "decide" with present simple to talk about scheduled future events or plans?

Thanks!

No, we cannot!
