It's a 110 crankset so the 34 low is already as low as it goes. Other cranksets make a plausible option but you have to go a little off-spec.

Probably the easiest: FSA is offering "adventure" cranks in 46/30, you can find the Tempo square taper version on eBay for <$100.
Mountain double cranksets have a chainline that's offset 2.5mm outward of a road bike so there's a wee bit more cross chaining once it's adjusted, but they are offered in smaller ring sizes, as low as 36-22.
You can get a MTB triple (42-32-22) or hybrid triple (48-38-28) crank and remove the outer ring. The result is near the correct chain line but it's not attractive because the outer ring is where they do all the styling.
You can get a road triple, but you'd need a different shifter and maybe a longer RD.

Cassette options.
There's a rare orphan SRAM cassette that goes 11x11-36. Your RD might make it. Not guaranteed.
You can get an XT cassette in 11x11-40. But you need a widget to space your RD far enough out to shift it. https://www.wolftoothcomponents.com/products/roadlink

All these options may involve a change in chain length.

And that's what you get when Dan can't sleep
