Can we stack multiple hats or use any unused pins when we use the respeaker keyestudio hat?

KEYESTUDIO ReSpeaker 2-Mic Pi HAT V1.0

I’m a newbie. I believe this hat doesn’t allow pass-through of other unused GPIO ports.

Is there a way to stack multiple hats, or does this hat actually use the majority of the pins?

Is there a way to at least use say GPIO x and GPIO y if they are unused by the hat? What I mean is that can I just cut off some of the pins that the hat has and not make it connect to the rpi?

Thank you!

If you want to use a pin, you can do this yourself by soldering the pins on the 2-Mic Pi HAT to make it connected
