^ You can peel it off, takes some time to get it cleanly off but it will work.
Have the same problem as you as well. What I did so far was take it to an upholstery shop where they shaved the foam down almost completely (thin layer left) and put the cover back on. it helped a ton in terms of getting me to flat foot/feel better on the bike. took of about ~1 inch i think.
Downside is that its super uncomfortable when I hit a bump in the ground/...... road and hurts my balls. I'm used to it now, but still working on a solution to make it comfortable. (One option I didnt try is to buy a gel seat you can put inside but that will detract from the height loss of removing foam)
I think I need to adjust my suspension to the softest settings (I'm also super light, only ~130 lbs). Not sure how to do that though
good luck man, let me know if you figure out any solutions
