In general, look for an option (setting) to do
this, if there isn't one, see if the interface
takes an argument (if so, write a small Elisp
wrapper that always passes the same argument
value), but if it doesn't, examine the code to
see where this actually happens, then remove or
alter it in a ~duplicated function.

I could perhaps offer better help, if I had
that function to begin with. But I don't and
I have nothing xref- at all actually. What is
it and how did you get it?

You can use this config:

(add-to-list 'display-buffer-alist
             '("^\\*xref\\*$" (display-buffer-same-window)))

xref.el was added in Emacs 25.1. From NEWS:

** New package Xref replaces Etags's front-end and UI.

The new package Xref provides a generic framework and new commands to
find and move to definitions of functions, macros, data structures
etc., as well as go back to the location where you were before moving
to a definition.  It supersedes and obsoletes many Etags commands,
while still using the etags.el code that reads the TAGS tables as one
of its back-ends.
