number of binds changing execution plan

Is there a parameter which we can set in the database that if we increase the number of bind variables in a query it's sql id and execution plan doesn't change

In my case there are 3 bind variables in query which runs in 11 sec If I replace a literal with bind variable resulting in 4 bind variables the sqlid changes and so is the execution plan.

Can we prevent such things to happen?
