ᐅ New efflorescence appearing all over the new retaining wall!

Unfortunately, our newly built wall has become an eyesore... Our terrace wall was supposed to be a highlight, but now I just want to look away. The manufacturer only says that we have to live with it and that it will disappear over time due to weathering. We were not aware of these issues with concrete blocks and approached the wall rather naively. What options are there? Without damaging the wall, making it look even worse, or just watching and hoping that after 3 years it might finally look like the wall was meant to...
