How to set ads priority in adsense

This is really a great question how to set ads priority in adsense? This is great because when adsense has more than 4 ads in a page then some ads are disable means some are not shown permanently but is there any way you can choose which adsense unit to display and which one not to because you never like that your high performing ads be disabled.

So I suggest that you do not create a situation for this to happen because there is not any way you can set the priority for the ads unit.
