I replaced the keyboard MacBook Air M1 keyboard with a $20 model from Amazon and it's been going strong for a full year. I had spilled ginger ale on the original.

The board is riveted in, but there are enough screws to hold the replacement in place. Removing the board is a shockingly violent process, but it worked for me.

Keyboard: https://www.amazon.com/dp/B0CQBVMM3X (price has gone up).

Video of rivets breaking: https://i.tonybox.net/9f2083b218d5.mp4 (you can see I missed a screw and slightly cut my hand here too).

Thanks for posting, I might attempt this if I feel brave enough one day! Mind if I link to this from the post? Could help someone in the future

wow, you are not underplaying the force needed. You can hear the rivets going.
