When in disassembly mode, you can move your point of view to anywhere, including from inside other objects, walls, floors, the ground, whatever. Anything that would block your view will disappear. So you can move your POV to wherever is necessary to see any screw or bracket that needs to be removed.

If part of the cabinet itself is in the way, that should be removable first. That's common for items that have a low bottom section on the floor - the front part of it comes off.

The default controls for moving your POV are to click and hold the right mouse button and then:

Move mouse left/right/up/down to rotate your POV.
WASD to move your POV left/right/up/down.
Use the scroll wheel on your mouse to move your POV in or out.

You can't nothing is removed all is with the red because you need to remove other parts that are covered in every way. The part on the ground you can remove one by one from the bottom but the wall you cant.

I just dealt with one of those. You lever off all the connectors you can reach, and that will let you remove the top of the cabinet. That frees up the back and then you can get to the rest of the connectors.

You can also toggle your setting to simplified dismantling for that piece if you know about it but don't want to deal with it.

This was the only way possible.

If you have a controller, connect it. Dismantling is so much easier as each part is automatically lined up. And shelf/wall that can be removed turns into a bright green light.
