Removing a RAM slot retention lever on my KGPE-D16

My issue is that my dual slot graphics card obstructs one of the PCI-e
slots as it is too long to place in the first slot without colliding
with one of the RAM slot retention tabs and I was wondering if there is
a way to easily and without damaging anything remove the RAM lever tab
and thus make it possible to fit the card in the first slot.

I do not need RAM in those slots as I only have one CPU but at the same
time I don't want to damage them.
