Answer 1

LINQ is for querying. You should use a foreach loop to make changes:

foreach (var item in custHead.lstCustomziation.Where(x => x.IsDefaultSelected))
{
    item.IsDefaultSelected = false;
}

That said, if IsDefaultSelected is false for the other items anyway, it may be simpler just to unconditionally set it:

foreach (var item in custHead.lstCustomziation)
{
    item.IsDefaultSelected = false;
}
