I don't know what this unit dashboard looks like but if it looks the same as other s19 model dashboards isn't the LSDIFF is what you looking for? it is on the dashboard under the pool.
Or check other monitoring software like APtool or awesome miner it might give a view about share difficulty.
its just odd because pool dificulty is set at 106k and seems like all shares showing on LSDIFF are a value of like 106060. The old dashboard had a box that showed "best share" which I can't seem to find with the newer version of dashboard. I'm used to gpu mining where I have a montior showing all shares/jobs that are being worked on
