If you want to make such a change globally, then edit the InlineCell 
style in the StyleSheet for the Notebook. You can use the Option 
Inspector to do this. Alternatively, unformatting the InlineCell style 
cell one will see:

   Cell[StyleData["InlineCell"],  
      LanguageCategory->"Formula",  
      ScriptLevel->1, 
      StyleMenuListing->None]

Modifying this to include the option

   Cell[StyleData["InlineCell"],  
      LanguageCategory->"Formula",  
      ScriptLevel->1, 
      StyleMenuListing->None,
      UnderoverscriptBoxOptions->{LimitsPositioning->False}]

will do what you want.

In this case you want to add the additional option

   UnderscriptBoxOptions->{LimitsPositioning->False} 

to the InlineCell style.

You will find these shortcuts under the

menus.
