I was wondering if the standoffs are removable?

You can use a wind gun to heat the PCB standoffs, try from a low temperature of 330 degrees, and we suggest you to use the high-temperature tape to cover the perimeter of the screen.
There is a 1mm thickness of 3M adhesive in the middle of the PCB board and the screen, which is not too heat-conductive. But pay attention to the air gun heating temperature, as well as the use of hot air gun technology.
This operation is quite difficult, may damage the screen. And this will make you void your warranty.
