If the B-ADJUSTER of this rear mech is UNSCREWED to the maximum limit, is the GRX -RX810 able to shift the chain on to a LARGER CASSETTE SPROCKET - either 36T or 40T ?

Have Shimano published any information about this ?

Can SJS or any SJS customer confirm this ?
Hi, according to Shimano the maximum limit is 34T. Thanks 08/04/2020
