I can't find a .duf of such a thing, it probably doesn't exist.
BUT... Daz can import OBJ, so here's one I just ripped from Sketchfab:

D/L: https://www.mediafire.com/file/xa2gc72c1k87fcp/boeing-e-3-sentry-awacs.rar/file
This package contains .obj/.mtl and a .blend, and all the textures in a separate folder, so you can edit this in any way you like.
Importing the OBJ right into Daz will probably give you a giant model without textures assigned. Just adjust the import scale (or scale it in Daz) and if you don't feel like assigning textures in Blender, you can do all that in the materials settings in Daz - the model should at least have proper material groups so it's just a matter of plugging in the correct tex image in the Base Color parameter for each material.
Let me know if you need any help 🙂
