if you go to edit --> feature --> suppress by expression, then you can pick the features you want to suppress which will allow you to turn the feature on by changing the expression between 1 and 0. Look at how the feature is displayed in the part navigator once it has been suppressed.
if you select all the components, right click on them in the ANT and select suppression, you can then say always suppressed, or even suppress by expression.
Assemblies --> components --> Edit component array will display a list of all the arrays and if you click one, it will highlight all the parts in the array. The suppess tick nox only suppresses the contraints. Other than that, I can't provide any more information. May JRB will be a little more useful than me.
Create a boolean expression "a" that control the suppression of the array template
Then modify the expression that controls the array size:
If a = false => array_size = 1 (the template only)
No matter how many components the array creates, it is always fully controlled
