What would be helpful is a straight-on image of the rear wheel and the RD so we could actually gauge ground clearance.
Example of straight on image:
GS on 53-406
Your GS RD looks like an pre-2017 Deore with a max cog capacity of 36t. Nowadays and since 2017 Deore GS has been able to span at least 42t.
