It's been integrated into COBL, but take heed that that mod is rather complex to install.
Duke Patrick's Combat Archery also has a denock function, but it's different than the one you're talking about.
I think COBL has a very simple installation, especially through BAIN. Anyway, yes, Denock is integrated into COBL, which many FCOM users use. Remove the separate mod, and enable it through COBL's in-game menu. (Click on 'Options+' in the misc. section of your inventory and enable it there.)
Happy Gaming!

Edit: COBL is packaged with an OMOD script as well, if you use OBMM...
