Having issues with setting up the textures of a model I'm making atm

Right now I’m working on a Carnotaurus model and so far these are my best scales yet, however there is an issue, this Carno is for a game on Roblox and due I’ve used subsurface to make the textures look the way they do, I’m trying to find a way to make it so that the textures are just a single normal map but still look the same (minus the slight pink tint since it’s just the normal map).
Here is an image of what the nodes in shading look like

and for why the subsurface’s change to the texture is so important, this is what the model looks like with it

and then without it
