I want to add power-ups, but I want to allow only the admin to use it
without the space members being able to use it. Is there any mechanism to do that?

As Trello is predominantly a collaboration tool so it is structured typically so that a Power-up is enabled for the board and thus all its members.  

However, some controls like you ask may be possible in certain power-ups.  What power-ups specifically are you looking to restrict usage of?

Like "cord snooze"

You could replicate that functionality with an automation button which you can create only for people you want to use it...

This does not mean
I only want certain people allowed to press and use this rice
