Disable username and password autocomplete on GITLAB users login form and upgrade JQuery


We have an account on GIT LAB which is self managed one running with 10.3.3 version.

Our security department complains that password autocompletion is possible for the password field in the web interface of gitlab login form.

I want to disable this auto completion of usernames and passwords for GITLAB login form and also i even want to upgrade jquery from 2.2.24 to latest jquery version on my GITLAB installed version.

I have searched the entire software tree for it but could not find it.

Can someone please help?
