I'm only half kidding here, but have you tried dyeing your hair, wearing slightly "younger" clothes, not including everything on your CV (and definitely no graduation year, etc.)?
It seems ridiculous but I wonder if it would work.
It's not ridiculous: I'm partly bold so I always shave my head. I tried to remove graduation years from my resume and did not find it's useful; it would only work if ageism was a sin of a few. Now I keep all my cards open: if my age would be the reason I prefer to skip erroneous interviews that hiding it would have brought (wasted 2 months and 4 interviews, Amazon, yeah?).
