Battlezone: Combat Commander

Vet Strategy Recycler Variant (VSR)
Can this be played without Steam (GOG version)?
I learned about the existence of this mod today and got super excited about giving it a go. Unfortunately, I purchased BZCC on GOG and I can't find any download links to VSR outside the Steam workshop, which doesn't seem to offer such. Is there a way to play VSR for me or am I stuck with the vanilla GOG version now?
