You can't have it both ways.
If you bind the value to the backing bean, then the value always
reflects what's in the backing bean.
You can bind it to a different backing bean property. Perhaps one
that adjusts the value returned by the getter for the first time the
page is displayed or otherwise delegates to your original
setter/getter.
You could try some kind of trickery and set the
processedSelectBooleanCheckbox component's submitted value to true via
java code on the first submit. There's a lot of unknowns in how
you'd accomplish this.
Realistically, though, I wouldn't be trying to change the
processedSelectBooleanCheckbox behavior. Instead, I'd probably
change the behavior of how your "value is displayed in a data table"
and accurately track the value of the checkbox in the property you've
bound it to.
