Front-matter parameter/variable or something...that could 'mark' a page to be published/unpublished?

Hi jekyllers

Posts can be i draft mode… Fine.

Yet, on pages…
Is there a front-matter little hack, parameter/variable or something…that could ‘mark’ a page to be published/unpublished or may have i dreamed it '?

i answer myself

published: false
