The best way to change an upper bound is to define a parameter to represent
it. For example, in this case, you could say
param x_ub > 0, default 1.0;
var x {i in 1..1000} >= 0.1, <= x_ub;
Initially x_ub will be 1.0 by default, but you can change this bound to 0.8
by means of the command "let x_ub := 0.8;".
