does the Gen3 GSD allow custom boost levels?

I haven't seen it mentioned in the reviews, but some newer Bosch displays support setting custom levels of boost. That would be a big improvement for me.

ECO is usually not quite enough boost, but TOUR is way more than I need. This was simple to adjust with Shimano STePS and Brose.

I believe you are looking for the availability to adjust your assistance levels? Yep! That is available for all smart system bikes through the Flow App
