c# - update multiple elements at once LINQ

Is it possible to set property on each element from List using LINQ.

for example:

var users = from u in context.Users where u.Name == "George" select u;

foreach (User us in users){
   us.MyProp = false;
}

Is it possible to make it cleaner ?

Or you can convert it to ToList() and use ForEach method.

users.ToList().ForEach(u => u.MyProp = false);

to update more than one properties

users.ToList().ForEach(u =>
                      {
                         u.property1 = value1;
                         u.property2 = value2;
                      });

Or like this

(from u in context.Users where u.Name == "George" select u).ToList()
.ForEach(u => u.MyProp = false);
