Whether or not the fungicide washes
completely off, I'll leave up to you. I know this.
When I was a 15 year old fresh to acid who had just moved to a different state and could not find acid (yet), I decided to try Morning Glory seeds.
I got horribly ill on 100 seeds, puking and the runs, on the toilet with a pot in front of me. Mild high (even for seeds).
Same thing the second time (

, damn kids).
After finally reading about the fungicide, I washed 100 seeds from the same batch. Got a typical Morning Glory seed mild trip with extreme lassitude. There was also mild nausea, but that happens with Morning Glory seeds.
Had 3-4 more trips from that batch with the same result, washing made a huge difference.
I'll leave it up to you whether or not I got
all the fungicide off. I, at least, got most.
This was 40 years ago, so I guess they could have a new poison now. All disclaimers apply.
One thing in your favor. The active ingredient in the seeds is inside that hard coat. Eating whole seeds does nothing. You could likely
scrub the seeds with no loss of potency since you are doing it before you grind them.
BTW, I also got mild nausea from Woodrose seeds taken right from the pod. Mild to moderate nausea is part of the game with the seeds.
