Sadly, I don't think you can. I'm assuming you're talking about the little black wedge on the ZIF connector?
I got round it but it's on a Pi that runs as a security camera so it never moves. I wedged a small piece of plastic in there that I cut from an old food storage box and then put a couple of blobs of hot glue on to hold it in place. It's been up for a few months now and seems to be fine.
