How to change criteria for searching on value set type field with a list of values

Summary:

I'm working on Core HR pages (Hire An Employee, Add a continget worker…) and I noticed that valuesets fields where the user can select from a list of values, are mostly Case Sensitive. Thus, they do not recgonize the strings if I'm searching with Caplocks ON. How can I change this, some fields in other forms are not case sensitive.

And also, How can I eventually change from the searching criteria from "Contains" to "Begins with" and Viceversa?

Is it even possible to do that from Visual Builder studio? Or should I use onother tool?
