Dynamic Lighting walls are pretty much all or nothing unfortunately. If there was just a single wall, I'd suggest creating an invisible token and giving it vision and that player control of it so they could see on the other side of the wall. But if it's a maze you'd have to do that over the whole maze. Instead, I would suggest perhaps simply duplicating your map (on the same map page, so you have two identical maps side-by-side) and do the same thing, but have one side with no dynamic lighting walls. Either the player will have to be savvy enough to look at both maps at the same time (if you explain that's what you've done) or you'll have to create a party token on the map with no walls that duplicates the movement of the rest of the party, or use a custom script to duplicate fake tokens on the wall-less map. Or someone else may have a better idea or a script that can do what you're looking for already. :)
