I know some farriers like for horses to be worked out right before they work on them. So maybe a lunge line session right before she gets her feet done? I don't have experience with this type of problem but I'm trying to help lol And maybe have the farrier do a meet and greet session instead of just going to her feet, hand her a few treats lol and few pats and just let them get comfortable. You need to find a farrier who is quiet, calm, and patient, but also knows his way around hooves.
