I took a few pics from the disassembled car I have in the garage.
I checked through my collection of Allen wrenches and didn't see anything that would be likely to clear (strut is fully bolted in).
Just a thought and NOT a recommendation... If I really wanted to access the strut without pulling anything off the bottom, I'd drill through the bottom of the clamshell pan and plug it after I was done. Maybe a slight risk of water penetration, but I don't think it's damaging to the structure.
