It's not screws.
I've looked into this to obtain more leg room.
There are bosses on the rear side of the bolster which protrudt through the dash panel, then the bosses on the bolster are heat-staked/melted onto the rear of the dash panel. So, you have to break stuff to remove it. One person on here has done it but they never posted any photos of what it looks like after. I believe you may be able to see some holes in the dash where the bosses protruded through.
Here's the original thread:
