This works for any mod.
Locate the mod folder withing the actual ARK game installation folder, not the workshop folder.

As an example with this mod having ID: 497432858 the full path on my PC is: E:\SteamLibrary\steamapps\common\ARK\ShooterGame\Content\Mods\497432858, your initial path will be different of course depending on drive and steam library location.

For single or a few entry changes just look for files with "EngramEntry_rest_of_file_name" and replace ".uasset" with "_C" at the end.
Eg:

"OverrideNamedEngramEntries=(EngramClassName="EngramEntry_v83Shotgun_C",EngramHidden=true)" in case of the Shotgunv83 for example.

For many engram changes and to grab all the engrams from a mod including subfolders open up a command window in the root of the mod folder and enter:

for /f "delims=" %a in ('dir /b /s *engramentry*') do @echo ReplaceMe01%~naReplaceMe02 >>engrams.txt

Then open "engrams.txt" in notepad and go to edit-> replace.

In find enter: ReplaceMe01
In replace with enter: OverrideNamedEngramEntries=(EngramClassName="
Hit the "replace all" button.

Repeat again this time:

In find enter: ReplaceMe02
In replace with enter: _C",EngramHidden=true)
Hit the "replace all" button.

Move the engrams.txt file out of the mod folder wherever you want to keep it for further editing, remove engram entries for the items you want to remain craftable in the game and then of course add these entries appropriately to the game.ini file.

I could not automate the entire process with my limited skills due to the required quotes causing issues with the "for" command.

Have fun!
