Damn! That's high!! You can certainly use aluminum sulfate as it WILL do the job - it's just that it will do the job SLOWLY... (I've seen some estimates of 6 months).... so I found an article you might want to read and figure out how best YOU can lower your PH... And next year, research this first, before the plants go into the ground... Most of the suggestions I've seen say to incorporate peat moss into your soil... so maybe with some amendments like that next year, you won't have the problem! (Pine needle mulch is another GOOD suggestion but takes a long time)...
Anyway, here's a link to the article... https://www.growerexperts.com/how-to-lower-ph-in-soil-fast/
Good luck! I hope you can get it down quickly!
