Disable word-wrap by default in Sublime "Find in Files" results

Yes, with the Find Results tab active (ensure the "Use Buffer" option is enabled in the Find in Files panel to get a tab instead of an output panel when you perform the search), you can navigate to the Preferences -> Syntax Specific menu item and enter:

"word_wrap": false,

and save it. This will ensure that word wrap is always disabled for Find Results.

(You can always turn "Use Buffer" off again afterwards, it's only necessary for the menu item to open the correct syntax specific settings file, which is Packages/User/Find Results.sublime-settings.)

In default, Sublime opens the files without word wrapping. If you want to enable it, just go to Preferences > Settings and add "word_wrap": true to the Preferences.sublime-settings file
