Hi @Aleksid1 - you don't need to do that just for this, simply look at /Library/Displays and see if you have any override files there under any of the subfolders for your display. For example:
Note, that to have 1280x720 as HiDPI option, you don't need any override files, since that is available by default in newer Monterey and Ventura versions.
