You can remove that feature from the GUI if you edit the javascript file.

I do not know if this has other ramifications, but you can test.
BE CAREFUL. EDITING THESE FILES IMPROPERLY CAN CAUSE MAJOR PROBLEMS.
MAKE A BACKUP OF THE FILE(S) YOU CHANGE FIRST
1> Go to the directory
/var/www/html/themes/tenant/_common/
2> backup the file " _menu.tpl " in this directory first. In case you have problems you can revert back easily.
3> Edit the file " _menu.tpl" and search for "password".
You will find this entry:
<!-- Profile sub-links -->
<li class="dropdown">
<a href="#" class="setadminpassword">
<i class="fa fa-user"></i>
{$CHANGE_PASSWORD}
</a>
</li>
3> Delete these 3 lines
<a href="#" class="setadminpassword">
<i class="fa fa-user"></i>
{$CHANGE_PASSWORD}
4> Save your changes and reload the web browser.
5> The change password option will be removed.
