U1 how to minimize prime tower in Orca?

Hello all. I am a new user to the U1 and Snapmaker Orca, but have been in the Bambu world for a few years now. I purchased the U1 to get away from large amounts of waste from color swaps, as the info stated repeatedly the U1 would have considerably less waste. Printed the “cute dragon” provided with the system and was astonished to weigh the prime/wipe tower and the dragon just to find the tower weighed almost as much as the dragon.

So I started digging in to SO and cannot figure out how to prevent flush purges into the tower when short wipes are required to build up pressure and clear any ooze. I seem to be looking for separate purge and wipe tower settings, yet don’t see them.

Is the solution to change all the flushing volumes to zero if I am not changing colors on a single tool head? If this has been answered somewhere else, please advise and I will happily trot off in that direction. Thank you.
