No, That isn't going to help any.
If I google your bike it shows a 48/31 crank and an 11-34 cassette.
so, if you are in the small chain ring and the large cog, you are at 31x34, which is pretty low.
On the crank, the difference between a 48/31 and a 46/30 is negligible. (the 48 and 46 aren't going to be used by climbing if you want low gearing).
you are already at the max size on your cassette (34). Typically on shimano, you can push it and go bigger, but that isn't gonna help a whole lot to go up a couple of teeth.
Eric went crazy on his GRX derailleur, but I'm thinking 40 wont' work on your ultegra. 36 probably, 38 maybe/maybe not
