In Tiles 2.0 never, in Tiles 2.1 there is a possibility.
*Don't* define the "breadcrumbs" attribute in "myapp.header" and
define a cascaded attribute in myapp.homePage and
myapp.homePageNoCrumbs:

<definition name="myapp.homePage" template="/layouts/page-container.jsp">
...
  <put-attribute name="header" value="myapp.header" />
  <put-attribute name="breadcrumbs" value="/tiles/header-breadcrumbs.jsp" />
</definition>
<definition name="myapp.homePageNoCrumbs" extends="myapp.homePage">
...
   <put-attribute name="breadcrumbs" value="/tiles/blank.jsp" />
</definition>

If you still are using Tiles 2.0, then you have to create a definition
that extends myapp.header.breadcrumbs and put it as the "header"
attribute in myapp.homePageNoCrumbs.
