How exactly does disassembly even work with this keyboard?

I have the board most of the way apart. The case is open, there are no more (accessible without a rotary cutter) screws anchoring anything together. Am I supposed to desolder the key switches in order to get the board to lift from the face plate or will the PCB survive a little bit of brute force and ignorance? I have absolutely nothing to go on here (I’ve hit a very similar stop with my Logitech G710+ keyboard, but that’s a question for that product’s dealie if a full teardown guide doesn’t yet exist).
